the dies i have for the 223 WSSM are RCBS like most of the other gear i have....using a bullet comparator and its zeroed to measure ogive COL......now when i measured the chamber it was 1.888 so thought i would start at .10 off the lands.....which is fine maybe a little long but it would be a start....the bullets are 55 gr NBT....now when i got it all set with a test shell it was dead on the $$ at 1.788....so charged up 10 cases and went to seating....i have a variance from 1.787 to 1.797....thought that was kind of odd...every other shell i have ever loaded with my RCBS stuff was within 1-2 thou...any ideas on what the problem could be?
my goal load for this thing is going to be for deer for my daughter and lookin at going with a 60 gr Nos Partition but got 250 of the 55 gr NBT left so thought i would at least get it shooting with them till i get me some of the partitions to load but i thought it was kind of odd to have that much variance
