As long as you know exactly what the cast bullets you use are made of and how they perform against stiff media I have no problem using them. When I killed that monstrous buff they told me no one had ever stopped one that fast.

I should add that I was involved in the load and pressure developement of loads for the .450 using bullets over 420gr so I knew exactly what I was doing. I would take your .454 and practice a lot out to at least 50 yards. Shot placement is everything on these critters. A piece of advice: If you plan on eating it shoot one less than 1000lbs. The smaller the better. Mine was over 2000lbs and the way to eat steaks from it was to stack them in a crock pot and cook them like a roast. It was tough.

When is your hunt?

The bullets from my buff:


The before clean up pics. They said there has never been a gun do what this one did to the buff including .375, .416s and .458s.
