What rifle are you shooting?
I have shot T7 in my .50 TC Hawken. 70 & 75 gr loads feel like 90 grs of goex. I just picked up some Pyrodex RS to tryout in my new to me Mowrey .54
So if my Kodiak riffle recommends a MAXIMUM of 150 gr. of Powerdex RS, or 3 50gr pellets, then I should be safe with 120 grs. of 777 ??
I have been shooting 100 grn loads behind a 240gr XTP sabo and wanting to "up the ante" on velocity, but have been affraid of blowing the gun up!
