I have been reloading rifle cartridges for 35 years and simply follow the full length sizing instructions on the dies which are all basically the same. Ram to top of press struck, Screw in die to touch top of shell holder, set 1/8-14 turn deeper.

I have had exactly 2 problems with not enough sizing. I do not understand all the fuss about "bumping" the shoulder.

Internet analysis: 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact

Fools & fanatics are always so certain and wise people are always so questioning
