338 lapua shell holder?

[MTDOGGER]

i just bought some new lapua brass and a #37 RCBS shell holder, well anyway i went to reload them for the first time and the brass would not fit into the shell holder, i miked it and going by hornady the inside rim should be .521 and the brass was .515 so it should have worked. anybody ever have this problem or is their a different shell holder that i should be using? thanks in advance

Use # 14

I believe the #14 is the one. Supposedly, the #37 is for Norma brass?

I bought Lapua brass and the same thing happened to me. The Reloading dies' box (RCBS) says #37 but it actually was #14. Luckily the local reloading store had it.

Lee #8 will work as well.
