A buddy and I are brand new to reloading. We have a Lee 1000 progressive reloading set for 9mm. On some of our completed rounds the primers aren't mounted flush to the bottom of the brass. By that I don't mean they stick out a ridiculous amount but you can feel it better than see it. Are those few rounds safe to fire? The over all length of the round is with in the specs set by the Lee Reloader booklet and the Lyman's recipe book we use. If they aren't safe to shoot could we put them back in the Primer seating section of the reloader to seat them deeper? Thanks!
