Again thanks for the response,
If he is able to use 150 grain charges with PowerBelts - I am surprised that they perform that well with that charge. When we got above 120 we were melting the skirt to the post + plus really jamming the bullet up against the bore - can not say we reduced velocity but the curve dropped sharply.
Accuracy or performance on paper has never been the question - that is one of the reasons the have sold so successfully - they are great on paper.
