Well a deal came up i could not pass on, Marlin 336SS 30-30 less than 50 rds for $300
From what i have read so far it's 10 twist with micro groove but i'm not sure how i should size my saeco 315 boolits.
Being a micro groove i'm thinking .309 instead of .310
I shoot this boolit in my 308 with great results in my Tikka T-3 sized .310 at 1850-1900 fps.
Dose this sound right to you that load for the micro groove barrels ?
Also i'm going to put a scope on and it came with a offset hammer something or other and i'm not sure what it's for or goes.
Any help for me ?
