Re: Savage 111 LRH 6.5-284 Loading Questions
The only suggestions I have is the same thing I have been suggesting. BTW- I don't the cleaning is causing it.
Do you have a concentricity guage?
Do you neck size and if so, what is the tension you are looking for?
My suggestion on powder and seating:
Seat .100 off lands and test with powder.
H4831sc. 54 grains was my max load. I would try 52 grains.
IMHO, .01 grains difference in powder is not going to make much of a difference. I think it is a waste of time and powder right now. It might make sense to test 51.5, 52, 52.5, 53, 53.5. One of those is likely going to be pretty good with .100 off. What do you have to lose?
