.338 Lupia Mag and shellholders

[FDLT406]

I am just getting ready to start reloading my .338 Lupia Mag and I am having a problem already.
I have S&B Brass which fits in a RCBS #14 Shellholder
I have Lupia Factory Brass that fits in a RCBS #14 Shellholder
I have HRTRS Brass that occassionaly fits into the RCBS #14 Sometimes loosely, sometimes tight, sometimes not at all.

I bought a RCBS #37 Shellholder and the only brass that fits it is Hornady, which I checked at the LGS.

Someone please have an answer to my problem.

Thanks, Fireman

There was some shell holder problems due to the 338 SAMMI specs not being standardized. I can remember if it was a brass or shell holder problem.
Best advice I can give you is, throw all the brass in the scrap bucket but the Lapua, it will save you lots of headaches..
