Thanks for the reply I will not be hunting just going to the range and enjoy shooting . I will not be loading the cartarge more than the factory loads. I would like to over proof the gun once as E.Brown describes in his book w/ a 30% higher load for one shot in each barrel. From what I read a 7% over charge will give a 30% proof psi load. Has any one done this w/ a springfield and what has been their experience.
