I to pour sour milk - but I can not praise really any Hornady bullets even though they are praised by most.
They come apart in under stress. If you stay within the velocity range they seem to work well but at the top of end of the velocity range you will find in SOME case the copper completely stripped from the lead and the lead spattered through out the chest cavity, or under the surface of the hide on the other side.
The animal will succumb to the wound at some point - but there are such better bullets on the market why not shot them. You might consider a .458 bullet instead of the .452 bullets. .458 (45-70) are rifle bullets and will hold up much better to the velocities of a modern muzzleloader.
