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

Don't know about Marshall's loads, but I've used the "Hank Williams Jr" load for years.

That load is a mag primer, 21.0 H4227 and a 255 SWCL. It gives me right at 1000 fps from a 4 5/8" revolver. I have fired a few from a carbine, and did not chrono them, but they slammed the informal targets I used.

That load, BTW, pretty much fills the case right to the base of the bullet. I don't think you could get more (if any) under a heavier bullet.
jjd45 is correct: they don't make H4227 any more. If you have a jug of it, however, the load data I quoted will work with either. (I have used both.)
