Everyone that has written talks about their great loads with this boolit.
I have shot it in my Contender (no throat so it get the bullet straight on), Blackhawk, Model 66 and now my GP100.
Powders I have tried, PS11, AA#5, HS7, 2400, WC820(110 speed).
Are you loading yours mild or wild to get the GREAT performance I keep reading about?
Heck, I'm gong to 4759 next!
So far (1 week and about 250 rounds) the GP100 likes the Remington SJHP semi coated bullet in front of 12.0 of "new" 2400!
