Hello to all, & Happy Thanksgiving! A while back I bought some of Marshall's 280GR WFNGC Sledghammers & he gave me a recommendation with this powder, but I don't remember the min-max charge weights. I'm thinkin he went up to 23 or 24grs max. Has anyone used this powder/bullet combo? I could use a little feedback. BTW, I'm using a Puma '92-20", and an Armi San Marco '92-24". Thanx for the help. jjd45
