I can't get my favorite - H4198. But I do have an unused pound of H322. I want to load up some 1700-1800fps 405gr Remington JSP fodder. Now I know I can get close with 50gr of H322, but I also know that it's not a sweet spot with my Guide Gun. Anybody play with this powder in the 45-70 and can give me some pointers? Thanks.
