[QUOTE="Long Time Long Ranger, post: 219176, member: 505"] Simply put, a lot of powder and a small bore. The 7mm rem mag and the 264 winchester are basically the same case but you go down from .284 bore to a .264 bore. With like BC bullets they get about the same velocity. The 264 winny is not a bad barrel burner by the way. Mine has been shot a lot for many years and is still a very good shooter. The 264 STW or 300 wby necked to .264 will have a short life of premium accuracy. These two along with the 7mm ultramag, 30-378 wby, 257 STW and a few more similar rounds are ones I have built that definitely began losing their accuracy after about 500 rounds and they just taper off until they are just not effective at all. If you get these type rifles zero and shoot sparingly for hunting. I believe practice with your rifle and a lot of shooting gets you very good with your rifle. Therefore if a guy saves his money for a top long range hunting rifle I always try to influence them to get a big 338. Nothing kills better at long range and they will last you a lifetime. There is absolutely no comparison to an animal hit with a big 338 and one hit with a smaller caliber. My favorite pet 338-378 has had the daylights shot out of it for years as a go to hunting rifle and it still holds extreme accuracy.
