[QUOTE="mnoland30, post: 1000739, member: 29323"] I know I can hit an elk at 300 yards, but I've been dissatisfied with the terminal bullet performance past 100 yards. Even at 100 yards, I seldom get complete pass through, so a shot right before sundown usually means you don't find the elk until the next day, if you find it at all, and once a bear found it before I did. I've tried Precision Rifle Dead Centers & QTs, Barnes, Hornady FPB, and SSTs. None of them have given me the terminal performance I'd like. I just read a PBS Archives of the West called "The Buffalo Harvest" by Frank H. Mayer with Charles B. Roth He routinely made shots at 300 yards on bison, and would drop most of them with one shot. He was using a 550 gr. bullet with a BHN somewhere between 10 and 11 (not hard-cast). He was launching these with a 120 gr. load of English made powder. I believe that muzzleloader bullets are too light. E. Arthur Brown claims that a sectional density of about .280 is about perfect. My experience bears this out. None of the major muzzleloader bullet manufacturers make a bullet that heavy. I'm shooting some 450 and 500 gr. bullets in my Kahnke muzzleloader (twist 1:26), but haven't found an accurate load yes. But I'll say that a 500 gr. bullet with 100 grs. of 777 (muzzle velocity of 1470 fps) kicks less than a 400 gr. bullet with 150 gr. of 777. Randy Garrett of Garrett Cartridge Co. claims that penetration for a .458 bullet is maximum at around 1250 fps. The reason magnums became so popular is that their point blank range is so long. Just point and shoot. With the advent of laser rangefinders and compensating rifle scopes, it just isn't that big a deal to hit long range targets with a bullet that flies in a rainbow arc. Terminal Ballistics Research out of New Zealand has done a lot of wound research. His claim is that the flat meplat on the front of a bullet causes an inordinate amount of damage, much more than a pointed tip or round nose. If penetration is optimal at lower velocity, and wound damage is extensive with a flat front bullet, then it seems to me I should be shooting the heaviest flat point bullet I can stabilize, and shooting it at a moderate velocity. Anyway, that's where I'm headed for my next elk hunt. I just ordered a couple of Lee molds in .457 dia and 405 and 450 grains. [/QUOTE]
