Ok in an attempt ot determine the COAL, I inserted a unprimed empty case with a Sierra 220 HPBT into the chamber and relaesed the bolt to seat the round. Ejected the round and measured the case of which was 2.322.
I understand that it is sitting right against the Lands so it needs to be back off a bit.
Sorry but another question, was this somewhat an accurate way to determine the COAL? If so, how much more should I seat the bullet to obtain the best results?
Once complete I can leave the seating die alone and move on from there.
Thanks again.
