Before getting my old safety prime working again with the new return spring I had considered priming by hand. The problem with that is that all I would be doing is adding more time to the job. Why have a turret press if I'm going to start doing individual steps separately. According to Lee I can upgrade to the new style return spring (actually looks much improved) on my Gen1 safety prime as long as I update to the newest plunger spring also. Up until getting the new "improved" version I had no complaints about the Safety Prime at all. I have loaded many thousands of rounds using it and now with the new spring I can hopefully get several thousand more. I think I'll buy a few extra springs though.
