Re: 6mm rem load data
47.2 grs H4831, CCI200, WW brass, Sierra 100gr SBT, COL is maximum to function in factory magazine (whatever that is). The barrel is a factory 22" bbl.
I very lightly touch the shoulder when using a full length sizing die.
I approached maximum in 0.3 grs steps.
Bare in mind the old 4831 powder was slower burning than it is now. I no longer have that old 788 and I not only reload for my Ruger #1. I use a lighter load in the #1, the 26" bbl makes for the lighter charge.
Bottom line approach maximum very carefully. Use a chronograph if possible.
