I bought 8 pounds of Varmint for the AR that likes to eat ammo. Got it cheap and it does real well in the AR as well as the bolt gun. I would like to try this with cast in the AR, bolt gun (223) and the 30-30. Anyone using this powder in any of these with cast? What about other calibers? No data that I can find for cast with this powder. Any help would be appreciated. Thanks
