Thread: tight closing the bolt

Yip, FL size them and try the resized case in the chamber before you load it. Believe it or not, not all dies, FL or NS are created equally. So a RCBS die might resize to just a minimal dimension different to say a Hornady die. But that difference in dimension could be important if you have a "tight" or fussy chamber. The same applies to brass - nearly every manufacturer of brass will have slightly different tolerances eg Lapua vs Winchester.
