Thanks for the heads up. Saw Bass Pro had H4350 about 10 days ago, but no Fed primers. I asked and 2 lbs was all they had left.
I bough 2k of the fed 215M's and 4lbs of H4350. If my rifle doesn't like it I can easily sell it and not loose and money.
My fear is it WILL like it and getting ahold of it will become a problem.
