I’ve had similar results with armscor myself and gave up on it a couple of years ago.Well picked up some blazer 9mm and armscor 357 magnum from cabelas today and went to the range today. Blazer tan fine but every single 357 round of the armscor ammo was out of spec as the overall length was too long and it would not chamber in my GP100. Returned it to cabelas and warned them they may want to pull the lot from their shelves as it would be dangerous to fire. Last time I take a chance on armscor.
