I have spent 35 yrs. running around in the mountains of mostly MT. And I have run into many a hunter packing a 300,338,340. But I have never ,personally run into some one packing a Lapua. Are these other cartridges better, NO, they are more common in backwoods Montana. Seen a few ultra mags on the trail. All the 338's make elk dead, and I have seen the most fall to 338 win, because it has been around for so long,everyone has one{not me}. All the 338 I like, you could give me any, for hunting, I would prefer up to the Lapua for recoil and performance. Like said look at the case capacities I posted and from how hard you want to push,and barrels etc, they split hairs. I dont have a lapua, but would love one. I would take a 340wm any day of the week,and have put many a bull in the dirt w/one
