I’m working with it in my 300 Sherman and in my 260ai. I'm completely amazed with it. More quickly than H4350, on par With RL16, but it's smaller sized and denser. I'm able to load additional powder at much less of a compressed load. I really like my new Ruger https://vihtavuorin13313471.liberty-blog.com/18476626/considerations-to-know-about-vihtavuori-20n29
