Thanks again
SL. I had a few disappointments. First, I forgot to bringthe dang fiber wads you sent along with the bullets. So I used some .54 Wonder Wads I had in my range box. Second, the battery on my chronograph was dead, so I didn't get to record velocity - which I really wanted to do. Third, the trigger on the Mustang for some reason returned to it's former gritty, creepy self. I need to pull it out and see what's going on.
Anyway, I can say with conviction that when you touch off 90 grains of T-7 under a 460 grain bullet you know you have shot something. Also, I had horrible crud ring with all four of those loads - but not with the Gold Dots (go figgure).
I really expected the .504 BSs to shoot the best of the group. Maybe I just shot a rotten round with that one - I've been known to do that.
Lots of questions. Would the fiber wad have been better than the Wonder Wads? Would 80 grainsof powderhave grouped better? Would Pyrodex have done better? Am I on my way to TotallyNuts?
