Using a Hornady comparator, I've found indicated base to ogive variations in a batch of 142 SMKs of 10 thousands / 0.010. This results in differences when I measure max cartridge base to ogive in my rifle chamber for each bullet length.
If my optimal verified seating depth with the bullet that measures 0.776 with max cbto of 2.265 is 15 thousands off the lands at 2.250 cartridge base to ogive, does this mean that the bullet that measures 0.765 and measures max cbto at 2.258 should be set back to 2.243?
Or do I have to test each bullet length? Or am I over thinking this?
Thanks
