That is because your not supposed to shoot 22 LR Long or Short rimfire out of a 22 magnum cylinder the mag has a bigger diameter case if you want to shoot the LR Long or Short you have to change the cylinder

Yeah, I understand that a .22 Magnum case is larger in diameter than a .22 LR case Gramps. The .22 Magnum bullet is actually a little larger in diameter than a .22 LR bullet for that matter. And I understand that because a .22 Magnum case is larger in diameter than a .22 LR case, if a person fire's .22 LRs in a .22 Magnum cylinders, it can, and has resulted in split .22 LR cases.
My question is why were the bullets "keyholing" at 7 yards? Ruger has probably built tens of thousands of Single-Sixes with interchangeable cylinders to accommodate both .22 Magnums and .22 LRs, but of all of those Single-Sixes, not one of them has an interchangeable barrel. Ruger's Single-Six barrels accommodate both .22 LR bullets as well as the slightly larger in diameter .22 Magnum bullets.
So I asked again; Why do you think the bullets from the .22 LRs fired from the .22 Magnum cylinder tumbled, resulting in keyholing at 7 yards? Could it be because they were out of whack when they entered the revolver's forcing cone? That's just a guess. I'm curious, that's all. :?:
