There's no need to complicate it if you're just practicing - Like your self, I have a dummy round (copy of PPU) to quickly set the die up - As I only use a low load (39 gn N140), I'm not too fussy about the powder or seating (maybe checking 1 in 5 to begin with), and can knock up 50 practice rounds, that still shoot well, pretty quickly...

...but if I'm loading for a competition, then I try to get the powder within 0.1 gn and check every COL...and it makes a significant difference to the group size.

37.2 Grns IMR4064
Hornady 150 Grn SP Interlock
Federal Match Primer
COL 2.935

Accurate as hell out to 400 yards, haven't tried them any further.

I am not complicating things, I have spent a lot of time and effort on generating a consistent round not to mention the time and expense of the kit and to be honest I enjoy the reloading just as much as going for a blat. I am simply trying to chase out the variables and this being one of them.

It ain't rocket science either and I understand that even the SMK bullets have some variables (but not as much as the PPU I used to fire) - The LEE seating die I use, would it make a difference to switch to RCBS dies for this? also whats the difference to the standard die, and the competition one???
