I have had a whitetail G series .451 for years. I have taken moose and deer with one shot kills. I use the lyman .451 495 grain volunteer bullets that I hand cast. These are great and are cheap to shoot. I use 70 gr. of 3f black powder. I have a weaver 4 power scope with an open circle at the crosshairs. I have given some thought to converting to 209 primers.
I write a bp column so I have lots of in-lines and I think the white is the best all round in-line on the market.
Good shootin!
