I have two Lyman deer stalkers in 54 cal one flint and one percussion. I just ordered 3 pkg of 444 powerbelts from Cabela's for 798 per PKG. question what would be best load to start wih in these guns. I am thinke 75 gr 3 f goex in the flint and 70 gr 3f t7 in the percussion. I think the 1x48 twist should shoot these ok.
