Just looking for some imput from you guys.Ive been working up a load for a new custom built 300 WSM.Im using norma brass 168 bergers & RL17.I have tried 59 to 65 grains and all loads give sticky bolt lift but not really flattened primer. Im afraid my original assesment that this gun has a head space problem.Looking for your thoughts or experiance.I dont feel that im off on my loads as I load 67.5 GR. in a factory 300 WSM. at max.load. Any imput would be welcomed.
