Fast twist 45. I can't remember now if it was shooting a lead 255gr KT, or a lead 280gr SAA.
That was the entrance side there, with complete pass through. Looked like an airport firetruck blowing foam from both sides.
He ran for maybe 40 yards, and pumped himself dry.
I got so excited on how fast you posted the pic I sent you I forgot to ask about how, what projectile, range shot and traveled distance of your buck.
That under hammer rifle is cool.
