Hi Robert, Hello to all,
I also use the RCBS 170 FN that Bumble uses. I have several 8mms and a .32/40, It works excellent in them all.
It casts nice bullets with plenty of lube capacity. I generally use a gas check and 15-18 grains of 2400, I'm sure that the bullet would handle more velocity, but it works for targets and plinking out to 200yds or so, thats all I ask.
