If you are using A-max bullets, get a Hornady manual too. They are a few bucks well spent.
The favorite powder for my Savage 22-250 is Varget. Your firearm may like something else. Dont be afraid to become a fellow addict to this obsession. You can have more fun trying different bullets and powders, so if you like to shoot, this is a great thing for you!
