Yeah sounds like a ot of factory ammo uses a blend of powders. I just figure if i can get the same bullets pushing the same velocity i should in theory get similar results. But as i said, reloading is new to me, so maybe im just being naieve there. Ive just never wanted to hand oad because i can afford factory ammo. But the way things are going, im not confident that ammo or components are ever going to be widely available again, so im jumping in the reloading game, like a million other folks, a wee bit late.
