You have been blessed for never seeing SP 45 ACP brass. I reload at a public range using a Dillon 650 progressive press. I spent over 15 hours (3 days) loading 2K rounds of 45 ACP using range brass. On the last day out of sheer disgust, I hand sorted the last 500 pieces to get rid of small primer brass. I used CCI primers, small or large, and did not change the anything else.
Mixed primer brass in a Dillon 650 can reduce the production rate down to 150 rounds per hour. The only solution was to carefully hand sort the brass. I bought a 5 gallon bucket of SP brass for $1.20 / pound. I'm going to shoot it at an outdoor range and leave the **** for someone else to enjoy.
I can easily make 700 rounds per hour with either 9MM or 40 S&W with good brass.
