I'm glad YOU said that stimpy,
I'm new to loading myself and ain't yet qualified to give advise, but from the burn rates of the powders he has and a desire to experiment some more (ain't that why we load, and how we learn?). Because H4831 is slower than varget, a faster burning powder than varget would fill the ticket.
H4895 is listed in a bunch of books in all the calibers he listed. Bluecollar wanted versatility and not a duplicate, so faster only makes sence too me.
I just got a pound my self, for the .223 and the 7-08,,Barnes lists it for the TSX in 7-08 and I want to try those. It's also a Hogdon "extreme" powder (like the varget I'm using) that they brag is not temp sensitive, and I think that's a big deal here in Minn, it can be 101 or -40,,I want to shoot all year long and still have a decent group in November for the deer hunt.
November isn't as bad a swing, I've only seen 70 too -20 through the years.
