I'm wondering if hand loads, using slower burning powders, would do better in a rifle. It looks like most of McShooty's ammo would be "normal" pistol ammo.
Is AA-9 (is this AA #9?) a slow powder? I'm unfamiliar with it.
An Internet forum is like having a friendly conversation over a drink at a local tavern.
Some guy at the end of the bar always has to stand up and shout something that makes no sense at all.
