[QUOTE="cowboyarcher, post: 764655, member: 14163"] Hi All, I've been kicking around getting into the bigger class of cartridges such as the big 338's or even into the 375's. I've been solely looking at impact energy as a comparison and figured it'd be capable on elk as long as I maintained 2000 ft/lbs or so. Obviously shot placement is key but I'm speaking about what the round can physically accomplish. But then I realized that bullet expansion is dependent on impact velocity. I've read that 1800 fps is a general minimum. With that in mind something like a 338 Lapua is dripping below that at something like 800-900 yards while carrying 2000 ft/lbs to more like 1200 yards. Something like the 375 Rum and a 350 gr SMK carries the energy to 1500+ yards but drops the velocity at around 1000 yards. So my question is this: Given a proper bullet, what criteria it meet to be physically capable on elk sized game at distance? Is it solely a function of impact velocity or energy? Thanks all and God bless you, Adam [/QUOTE]
