270 winchester vs 308

As the bullet moves downrange, it loses altitude. While we agree that energy is important, we also think shot placement is as important if not more. Huston is a hunting enthusiast who believes your success in the field is directly correlated to the amount of preparation at home. To be more confident that this trend is the norm, let’s take a look at the average BC for these two cartridges with larger sample groups. As the rounds move downrange, we do see the .308 Win rounds start to lose momentum at a faster rate than the .270 Win rounds. The data that we have from the large sample is almost exactly the same as the averages from the smaller sample size. They formally released the resulting .270 Winchester cartridge in 1925 with the Winchester Model 54 rifle. J’en connais deux en utilisation mixte, battue de gros et chevreuils, dont l’un est utilisé en plus pour le chamois en haute montagne. There are some trends between cartridge types though. Besides, with that adrenaline pumping, you’re not going to feel it anyway. .270 Win vs. .308 Win 12-06-2016, 07:16 PM. While they have some similar characteristics, there are differences that make them better in certain situations. Both are great, but you should hunt with ... or to learn about how the .270 compares to the .308 Winchester, or to learn about other cartridges specifically designed to improve upon the performance of the .30-06, read the articles below: 308 vs 30-06 vs 300 Win … Pas de choix de grain (130-140-150Gr), Vitesse ultra trop vite pour la chasse de proche, certain s'en servent pour toutes les chasses, même le Coyote et la Marmotte. Jack O’Connor, a famous writer of firearms and hunting, really pushed this cartridge and its abilities in the field and brought it to the forefront of hunting cartridges, where it remains to this day. The extent of this difference may or may not be enough for you to decide one way or the other. 4. penetration. So while this method for comparing the .270 vs .308 is cleaner, all of these different aspects should be taken together to give you an idea of which cartridge is going to be better suited for specific applications. Where I personally live we are in a slug only zone and I have a savage 220f to take care of that. Get our PDF with 13 pistol & rifle targets (worth $48) including expert instructions for FREE! Both cartridges have the same .473″ rim diameter. My shots rarely exceeded 125 yards or so in the foothill country that I hunted in central Wyoming. Both cartridges can be chambered in AR-style rifles. beat. Even with these various variables, we have kept everything as constant as possible, and the trends that we see should hold up. Accuracy has more to do with the quality of the firearm and the user more so than the cartridge. It is important to note that what we are comparing here is straight recoil energy. Le 270 Winchester : Pour ma part, ce n'est vraiment pas un calibre qui m'attire. Both the .270 and .308 will work extremely well under those conditions and there is very little difference between them at short range. I’m more than happy to shoot inexpensive bullets like Speer Grand Slam (180 gr and 175 grain, respectively) out of a 308 or 280 Rem. On the other hand, since it shoots heavier and larger diameter bullets, the .308 Winchester has a clear advantage when hunting larger species moose, elk, and caribou. One has its origins in the military while the other was manufactured for hunting. Il est très adapté pour la chasse en montagne, grâce à ses aptitudes pour les tirs à moyenne et grande distance. Instead of .284″ bullets like the 7mm Mauser (and more recently developed cartridges like the 7mm-08, .280 Remington, .280 Ackley Improved, and 7mm Remington Magnum), the .270 Winchester used .277″ bullets which undoubtedly hampered adoption of the cartridge to a certain degree. Before we discuss any differences and trends that we see between the .270 vs .308 in sectional density we want to take a look at two rounds of the different cartridges that share the same bullet weight to show how sectional density can differ based on the variables that go into calculating the sectional density. Longer track record. I decided to compare these three because the 6.5 CM seems to be widely … Table below compares the four different Federal Non-Typical Whitetail loads: 130gr (.372 BC) and 150gr (.261 BC) loads in .270 Winchester and 150gr (.313 BC) and 180gr (.382 BC) loads in .308 Winchester. For recoil, it’s a wash between these two cartridges. Now the .308 Winchester is a perfectly capable long range cartridge and plenty of hunters use it on mountain hunts each year. The .243 Win is a necked down version of the .308 Win and was introduced to the shooting world in 1955. This scenario is also omitting bullet design, which in real world scenarios, is just as important as any of the data we are looking at. Recoil (sometimes called “kick”) is the rearward movement of the firearm when fired. Both are also great for similarly sized game like black bear, feral hogs, javelina, mule deer, and pronghorn as well as exotic game like axis, sika, and fallow deer. The Federal Vital-Shok Nosler Partition 150gr is one of our favorite hunting rounds for the .270 cartridge. What exactly are the differences between the two cartridges and how do you choose between the two for hunting? Among many others, Browning X-Bolt, CZ-550, Kimber Hunter, Mossberg Patriot, Nosler M48, the Remington Model 700, … For shots taken at extended ranges, a higher BC often means fewer adjustments will have to be made to get the bullet on target. .270 Vs. .308. Both are fantastic cartridges that have been tried and tested in the field for decades. For this reason, the .270 Winchester is used in standard/long action rifles, while the .308 Winchester is the poster child for short action rifles. But, advancements in ammo propellant allowed Winchester to develop a smaller round with similar ballistics to the .30-06.. Providing approximately 90% of the power of the .30-06 in a smaller package, the cartridge soon became very popular and is now one of the most widely used big game hunting rounds in North America. Do you primarily hunt deer sized game (including black bear) at ranges less than 200 yards? I also think the heaviest bullet for the .308 should be no more than 165 grains. However, the .308 performs better with heavier bullets than the .270 and is available in a wider range of bullet weights and models. These two numbers are pretty dang similar. Though only a few cartridges use .277″ bullets, the .270 is extremely popular and there’s a plethora of quality bullets to choose from. The .270 might be a better option when dealing with shots that are over 400 yards. .270 will have more recoil and a bit more power but .308 has more choices for ammo, unless you reload your bullets then you have about equal choices. As for the penetration potential of these cartridges, the .270 Win rounds had slightly better SDs than the .308 Win rounds but the .308 Win rounds brought a little more momentum, especially at the more common hunting ranges out to 400 yards. Again, no substituent exists for proper bullet placement. Not surprisingly, pretty much every ammunition manufacturer of note like Barnes, Black Hills, Browning, Federal Premium, Fiocchi, Hornady, Magtech, Nosler, PMC, PPU, Remington, Swift, and Winchester (just to name a few) produce a wide variety of ammo for both cartridges. .270 Win. Historians say Winchester engineers actually used the 300 Savage, a 1921 release, as the … Sniper Country is reader-supported. The absolute cheapest .270 Win. This long line isn't all of the 30-calibers on the market, either. The more pronounced this bullet drop, the more difficult it is to make adjustments to shot placement. Anything within that yard mark is no issue. If we take the average of the given rounds, we see that the .270 has a slight advantage with only a hundredth of a difference. Let’s see if the higher muzzle velocities of the .270 Win rounds holds up when we add more rounds to the group. The rifle situation is very similar to the ammunition situation with these cartridges: .308 Winchester is by far the most popular with the .338 Federal and .358 Winchester, in that order, following far behind the .308. From this cartridge, the 7.62×51 NATO round was also designed and saw brief use in the US military in Vietnam with the M14 Garand. What we will see is that there are quite a few similarities between these two cartridges as well as some small but significant differences. The same can go for the .270. And there is a reason that sectional density is not used as the sole metric to determine potential penetration. In the end, the best cartridge all depends on the type of situation they will be used. On the other hand, the majority of .270 Winchester factory loads shoot bullets in the 120-150 grain range. And when we are talking about extended ranges we mean 400+ yards. Again, 270 is a fine cartridge, but whatever you shoot, you need to understand that cartridge’s limitations. Testing rounds on ballistic gels are one method of testing the penetration between two cartridges though how well a gel simulates a bull elk is up for debate. The ballistic coefficient (BC) is a term that elicits a lot of attention from hunters and marksmen, or it’s a term that they don’t know a whole lot about. This carbine is my favorite for deer sized animals. Additionally, the Browning X-Bolt, Kimber Hunter, Mossberg Patriot, Nosler Liberty, Ruger American, Ruger Hawkeye, Savage Axis, Thompson Center Compass, Tikka T3, and Weatherby Vanguard are available in both calibers. All cartridges/rifles are a balancing act between The nice thing about the 270 Weatherby is you can shoot Sierra 90g HPBTs at 3700 fps for varmints, 130g Partitions at 3350 fps for mule deer or sheep … When we look at the numbers for our larger data set, we see the same trends as previously. If you fired these rounds from your platform, you would more than likely you’re going to see numbers that vary from what you will find here. Mar 14, 2011 #1 ... That said, a Browning .30-06 w/ a synthetic stock & a .308 Winchester Lightweight Carbine (6 lbs, unscoped, 20" barrel) are always the 1st guns I grab for any hunt anywhere. Note: there is quite a bit of overlap with the performance of various 150 grain loads for both the .270 Winchester and .308 Winchester. From a hunting perspective, momentum is a good indicator for potential penetration, like sectional density, and really goes hand in hand with it. 1 of 2 Go to page. So where do we stand with each cartridge? If we step back and look at the two cartridges, we see some pretty interesting results. Like the short-range trajectory, this data originates from the manufacturer where the zero setting was set at 200 yards and the measurements taken out to 500 yards (Graph 7). Thread Status: Not open for further replies. Specifically, the military wanted a new rifle chambered in an intermediate cartridge, capable of automatic fire, and equipped with a detachable magazine. P.S. For hunting cartridges, the stopping power is one of the more important performance characteristics. For the muzzle velocity, we used the data provided by the manufacturer so take that with a grain of salt as well. In 1925 Winchester necked down the .30-03 to .277 and created the .270 Win., a sporting cartridge designed for medium-size game that shot flatter yet recoiled less than the .30-06 Springfield. They named this round the .223 Re… Pas de choix de grain (130-140-150Gr), Vitesse ultra trop vite pour la chasse de proche, certain s'en servent pour toute les chasses, même le Coyote et la Marmotte. Please note, the following information reflects the estimated average ballistics for each caliber and does not pertain to a particular manufacturer, bullet weig 223/5.56 vs 7.62×39: Everything You Need To Know. Both BDL's. BONUS OFFER: Get your 500 Page Ammo Comparison Handbook (worth $43) for FREE right into your inbox. The .270 Winchester was introduced in 1925 where it would stay in relative obscurity for a time. History of the .223 Remington. While the .270 had a very high muzzle velocity compared to other popular cartridges of the day, it was not an instant commercial success. The .308 commonly has a 150 to 180 grain range. From this graph, we see that there is no noticeable difference between the two rounds to the 200-yard mark. These diameters play a role in the weight of the bullets that are used by the two cartridges and in other performance specs that we will look at later in the article. To put this into perspective, a Boeing 737 commercial airliner travels at a cruising speed of 600 mph, or 880 fps. We used a common grain powder load for each cartridge type that we determined from Nosler load data as well as assumed that the cartridge was being fired from a 7lb weapon. It is great for hunting big game such as moose and elk, although while talking about the .308 vs .270… So the 270 is a slightly less punishing round that should allow for faster follow up shots if need be. When used in the right scenario, both the .270 and .308 are effective cartridges for bringing home game or smoking the competition on the range. The .270 with a 150-grain bullet has a speed of around 3000 feet per second when leaving the muzzle. So, let’s take a look at the sectional densities of the ten rounds we have been using for comparison and see if any trends emerge (Graph 9). Where calculations are made, we will be sure to make clear our variables. After all, the recoil of the .308 is very similar to the .270. U.S., Canadian, British, and other allied nations used the cartridge at the start. Two of these components that we will look at are the kinetic energy that is associated with the bullet as it travels downrange and the how well the bullet penetrates the target. We do know that there is a lot of variance between the individual rounds, but the top performing rounds in this category are .270 Win factory loads. We already know that the .270 Win rounds have a smaller diameter than the .30 cal cartridge and when we added in more rounds, they contained quite a few heavier rounds that bumped up the average. The .270 is fitted with a .277″ diameter bullet. And while we don’t think ballistics can rectify user error, we do think that certain ballistic characteristics can help you be more accurate on a consistent basis. ; They are certainly both capable of cleanly killing a deer. According to Hornady's website the best 130 grain 270 loading has an identical drop at 500 yards as the … I have two favorite rifles, a .308 and .270. Those efforts bore fruit a few years later with the bolt action 1903 Springfield rifle chambered in the new .30-06 Springfield cartridge. While there are some rounds from each cartridge that are pretty similar in velocity, the trend of the .270 rounds having an average of 200-300ft.sec more velocity than the .308 rounds extends out to the 500-yard mark. While the .308 produces slightly more recoil energy (21.7ft.lb compared to 19.6ft.lb), it probably isn’t anything significant, especially to more experienced shooters. for longer range better go for the 7mm Rem Mag or 300 Win Mag/300 Wby Mag with 180gr. The sectional density of a bullet is derived from the bullet’s weight and diameter and correlates to its penetration. By the time the rounds reach the 300 yard mark, there is only 4lb/ft.s of momentum difference between the rounds of the different cartridges. Both the .270 and 7mm mag. For instance, the 150gr Nosler Partition below really did a number on a big kudu bull in South Africa. With a degree in Microbiology and several years of doctoral work manipulating bacterial genes, he attempts to merge the rational and unbiased thinking of scientific research with the passions of hunting and fishing. Hitting small game with a heavy grain .308 is not going to leave anything behind and is just overkill and a waste of money. It’s also important to remember that expansion of the bullet is also important is this allows the maximum amount of energy to transfer to the target. C'est même un des pire. What should be taken away here is that both of these cartridges have rounds that are going to range in sectional density. For instance, though it’s possible to find .308 ammo shooting bullets weighing as little as 110 grains, most .308 Winchester factory loads designed for big game hunting use heavier weight bullets in the 150 grain to 180 grain range. That not only pertains to the ballistic categories but other performance categories as well. The .270 can be thought of as a necked down version of the .30-06. While the .30-06 was meant for rifles with a long action, the .308 was … Both cartridges have the same .473″ rim diameter. This round is affordable which is an important consideration when you plan burning through quite a few out on the range. When you buy through links on our site, we may earn an affiliate commission. The reason for this is the smaller diameter of the .270 allows more force to be localized to a smaller area and helps push the bullet deeper. By looking at this information, we hope to better tease apart which cartridge is better suited for specific hunting situations. The 270 vs 30-06 debate has gone on for about as long as the .270 Winchester and .30-06 Springfield have existed. I've only practiced with two rifle calibers, .22 short/LR and 7.62x39. The faster 150 grain bullets were tried for mule deer but I was disappointed with the significant meat damage. Unfortunately, we are limited in our available space and decided to cut the samples off at ten. This fits with the original intent of the designers interested in building a mild shooting and easy to handle cartridge that was still powerful enough for hunting medium sized game at short to moderate range. In this table, we have actually extended the range out to a 700 and 1,000 yard marker. Again, there can be a lot of variance on the BC from one round to the next of the same cartridge depending on bullet design. With only four thousandths of a difference between the two averages, it doesn’t make much sense to make a choice between these two cartridges based solely on the ballistic coefficient. Introduced in 1925, the .270 is 92 years old; the ’06 is 111. This long line isn't all of the 30-calibers on the market, either.
