Buckstix,
"It isn't worth risking damage to a nice gun, just to save a few dollars."
I certainly agree with you on that.
I would not go over .327 in my case, and the weight is off as well.
I have actually some PRVI on order, but it certainly won't be my first try.

As for the loading I am converging to the *ball park* of 40 grs of IMR4895.
