HI Ya Dave,
the barrel is .3545 and the bullets are .356, i think that is good dont you?
the keyholing was at 3.5 and 3.7 grains. today i will try 4.2 which is a bit over the book. as i said i will run a couple thru my Blackhawk first and see if the primer looks good.
wish me luck!
much obliged,
max
