Re: reloading press
If the ram is square or not, which I'm sure it probably is, doesn't really matter. When you set your dies to bump the shell holder on the top of the stroke, it squares the die with the shell holder, which squares the case also. There's probably more slop in the fit of the shell holder into the top of the ram than there is between the ram and the frame. If you didn't have some clearance you wouldn't be able to get a shell holder in and out.
IF YOU'RE SHOOTING DEER OR ELK AT 1000 YARDS, YOU'RE NOT HUNTING, YOU'RE SHOOTING.
THE SHOT IS THE TROPHY.
