"The .260 Remington blows .308 out of the water. It has 35% less wind drift and about 10 MOA less drop at 1000 yards than the standard 175-grain M118LR load. Despite a 35-grain deficiency in bullet mass, it has 31% more energy because it loses less along the way due to atmospheric drag, hitting 350 fps faster at 1000 yards." |
Howdy myfault. The article that you list has some truth to it, and it also has ALOT of BS that is just touting the horn of the .260. I can tell you for a fact that there is NOW WAY IN HELL that the .260 will outperform the .300 winmag at long range. What I think is funny is that they compare the 140 grain bullet from the .260 at 2840 fps to the 190 grain bullet out of a .300 winmag at 2900 fps. This means that they will probably have close to the same time of flight, because the .300 winmag bullet starts out faster, but according to them, losing velocity faster because of the aerodynamics of the 6.5mm bullet. Even if this is true, if they have close to the same time of flight, then the .300 winmag will have LESS wind drift because it still weighs significantly more; at the very least it would have about the same. The other thing is that I have seen LOTS of .300 winmag loadings that push 190 grain bullets around the 3000-3100 fps mark, especially out of a 26" barrel. They say that it pushes those 140 grain bullets at 2840 from a 26" barrel, I'm guessing they probably used a 24" barrel on the .300 winmag, you give it a 26" or 28" barrel and it'll be smoking that .260. There are also extremely high BC bullets for the .30's that I'm sure they did not use in this comparison. If you used a Lost River Ballistics bullet (who got bought out by hooker I believe), those high BC bullets would put the .260 to shame. If I'm not mistaken, I believe that lost river ballistics had a 180 grain bullet that had a BC of .9 or something ridiculous like that.
Please keep in mind that I'm not saying that the .260 is a bad cartridge, I'm just saying that some of what is in that article is hype. I'm also saying that especially if you don't reload, there are much more feasible calibers for you to choose from that would probably fit you better. Have you ever shot out to 1K? If you haven't and most of your shooting is going to be at 500 or around that area, you're probably not even going to notice most of the difference. That article does have some truth to it though, that the .300 winmag 7mm mag, etc will have more recoil and burn through barrels faster. That's the price you have to pay if you want the advantage in firing heavier bullets near the 3,000 fps mark.
