I've struggled for years to find a bullet that would give pass through performance on elk at 200 meters. I tried Barnes, Shockwaves, FBPs, Precision Rifle 400gr. QTs, and was not happy with any. Pointed bullets slip through the skin and seal the hole behind them, and there is no exit hole. I killed elk with all of those, but sometimes had elk run away with no blood trail. Sometimes I would find them, and sometimes I didn't. Part of my problem was that I was using 150 grains of 777. Higher velocity reduces penetration. The bigger problem is that almost no one makes a muzzleloader bullet with a Sectional Density of .270 or more, which is what is recommended for elk. I finally found an affordable solution with 405 gr. Remington .458 bullets (for .45-700) with Harvester Crush Rib Sabots, and 115 grs. of 777. Sadly, after the Obama ammo panic in 2008, the bullets are no longer available. I have had very good success with these bullets, with two cow elk dropping in their tracks, and complete pass through. Anyone else using .458 bullets with success?
