[QUOTE="Long Time Long Ranger, post: 368908, member: 505"] I agree, with that many boxes of brass for the 340 that is a good choice. Just not much real difference in the big 338's. I have shot them since the 70's and built many of the latest and greatest as they became available such as the ultramag and lapua cases. For instance out of a 28" barrel with a 250 grain bullet the 340 wby will get over 3000 fps, The 338 ultramag, 338-300 ultramag and 338 lapua will get over 3100 fps. The 338 lapua improved will get over 3200 fps and the 338-378 wby will hit 3300 fps. That is real data averaged from many big 338's over a chrono at top velocity. A fast barrel or a slow barrel will get outside these norms a little but this is what you can expect on average. Any of these will kill elk size game at distances well beyond where most hunters could ever hit one. [/QUOTE]
