By Chuck Hawks. If you could only own one over the other, chances are good you would find more practical use for the .308 round, simply because it’s a longer distance shooting round and can be used to hunt almost anything in North America. None of the other components do us much good if the round isn’t put where it can do some damage. I evolved over the years from 12 gauge slugs to 30-06 to 308 to 7mm to now .243. Given your criteria I'd five a close decision to the 270. Just because of the nature of these two cartridges, there is some difference between the bullet weights of these two rounds that we have no control over. For the .308 Win, we like the Nosler Ballistic Tip 165gr. Recoil is expressed by feet per pound, and so long as the weight of the actual gun you’re using is the same, the .308 produces much more feet per pound than the .243 (as much as nearly ten feet per pound more). We also have to weigh the impact the light .243 varmint rounds are having on this average as we did with the velocity. I can get Remington or Federal loads for $15 a box when they go on sale. As we go through these various categories, keep in mind that they all play off of one another and all influence the performance and profile of each round. 308 will have MUCH longer barrel life, more recoil, more downrange energy in you are a hunter. At the five hundred yard mark, the bullet energy of a .308 will fall to around 1,500 feet per pound. One of the biggest reasons for this is how quickly the 55gr .243 rounds bleed off velocity. Because stopping power is a culmination of a lot of different factors, we don’t ever try to get into the argument of which metric is the best indicator of a rounds stopping power. There's a lot of debate as to what the best deer rifle is, but the .243 definitely has it going on. The .308 has a bit of a kick, especially when compared to the .243 and might be a bit much for users that don’t have much experience with firearms. We also have bullet B which is also 100gr but with a .200 bullet diameter. With this information, we can begin teasing apart where these cartridges would be better suited. For hunting smaller game such as coyotes, bobcats, ground squirrels, prairie dogs, badgers, varmints, and so on, there is absolutely no question that the .243 Winchester round is better suited for the task. Jun 10, 2008 #2 Around 20 deer total and For hunting purposes, this shouldn’t have as much an impact on your decision making since responsible hunters are not taking shots at this distance with these cartridges. But at the same time, the difference in SD between a .308 and a heavy .243 is very minimal, which suggests that their penetration would be roughly the same, with a slight edge going to the .308. The .243 has options for some hot rounds, but the hot ones, bleed velocity quickly and by the time you get out to 500 yards there is not much difference. glennasher1 Well-Known Member. Guess we were placing our shots in the wrong place with the .243. And we realize that most of you are already aware of what we are about to say, but trajectory is far from the only performance spec that needs to be considered when thinking about a cartridge you are wanting to use. We are looking at the velocity (ft.sec) from the muzzle out to 500 yards in 100-yard increments. Meanwhile, the difference is much more meaningful when you are using a lighter .243 load, which has a much smaller SD. 898 Posts . Of course, the energy generated is going to vary from round to round even within the same cartridge type. The.243 Winchester is simply the.308 Winchester necked down to hold.243″ diameter bullets. With such a disparity between these two cartridges, let’s take a look at more rounds and see if the gap widens or closes. Thanks for your time spent on this article. So these rounds are not influencing these averages any more than a lot of the other rounds do. Sometimes referred to as the little brother of the .308, which we are sure it doesn’t appreciate, it is important not to let that comparison influence how these two cartridges perform. It can accept bullet weights from fifty up to one hundred grains. Meanwhile the poor little 243 Winchester, which is the 308 Winchester case necked down to accept 243-caliber bullets, is suspect. .243 vs .30-06; If you have lung tissue you should have a dead deer within 60 yards, More likely 40 yards. The.308—a fine design in and of itself—has been responsible for a number of successful cartridges, but the.243 has to be the most successful. This isn’t just subjective, as it’s really a scientific fact. Both use the same parent case, but the .243 is better suited for small game hunting and varmint shooting and the .308 for bigger game hunting and tactical use. The same trend continues at the 300-yard mark. We mentioned earlier that there are rounds where the ballistic coefficient is a bit closer between these cartridges, but overall, the averages give an advantage to the .308 Win rounds. In this department, the .308 is undeniably more popular. Especially if it is hunting, where stopping power is as critical and is the subject of our next section. While the .308 does have a history in tactical applications as well, it is not often enough for us to focus on that area either, especially with our second cartridge being the .243 Win. Even so, the biggest difference in trajectory is not until the 500-yard mark where we re only looking at five inches of difference, at the most. 243 vs 308 - Die hochwertigsten 243 vs 308 im Vergleich In dieser Rangliste finden Sie als Käufer unsere Liste der Favoriten der getesteten 243 vs 308, wobei die Top-Position den Testsieger darstellt.
