Thats some good info there Mike, even my 5.5" barreled .44 58' has some decent ballistics with .457 143gr. Ball.
I'll have to agree with HH in the penetration, because I've shot a 320gr. .512 Lee REAL Bullet out of my Bobcat with 100gr. of FFFG Goex & only penetrated through a Steel Mess Kit Pan & 5 inches of Packed magazines at 100 yards, a RR tir is a pretty thick & tough piece of wood.
