Forgot to mention barrel erosion. The Lapua will eat barrels faster as well, no new news there. Accuracy depends mostly on the rifle and shooter but the argument can be made for a shorter powder column and lower velocity. The belted cartridge with a full size rim is much stronger than a non-belted cartridge especially if it has a rebated rim as well. This make for more positive extraction in the case of sticky cartridges, something important with charging bears but of no life or death concern to paper punchers.
Shooting game animals at 1,000 yds? Who do you think you are White Feather?
Not an ethical shot any pro guide would endorse. Hitting the animal in the wrong place would allow the animal to run awhile before sufferng a lingering death. Niether would be guaranteed to penetrate well at that range on large CXP 3 game. It is an internet dreamers shot not an ethical one.
