Still, there is no excuse for a round stuck in the barrel, the way some folks shoot you are looking for a serious accident by shooting another round behind the first one. Each case must be checked for a proper powder charge as a last step before seating the bullet, if you're using a progressive and you can't check, either visually or mechanically, use a single stage press. You should not be content with"an occasional squib, or no powder round", your health(eyesight) depends on your good loading practices.
Old Saying...
THERE ARE OLD RELOADERS AND THERE ARE BOLD RELOADERS BUT THERE ARE NO
OLD BOLD RELOADERS!
I have never had a squib yet...so knock on wood.
