Thanks for all of the comments guys, I'm really anxious to see what she'll do.
Roger I'll be sure and post a range report, I got it just in time for deer season, I think the fellow was dissapointed that I was taking it to the woods but I promised him I would take good care of it and would not be climbing any trees with it, I haven't killed a deer from a tree stand in over 10 yrs and never have any problems killing deer.
Daryl,
I thought I would start with 90 gr of ffg Swiss, it shoots pretty well in Larry's .54 Rice bbl, I will have to take inventory, I think I only have .535 balls left, since the only other .54 I have is a heavy bench gun, I never needed .530's. The fellow that built it never shot it but had other .54 GRRW barrels and said they were a little tight with .530's I'll just have to see what works, that's part of the fun.
I had a choice of 2 guns almost identical, the other is a.58 which I would have preferred but I liked the butt plate on this one a lot better, the .58 was round on the heel, I'll post a pic of that one when I get a chance.
Regards, Steve Chapman
