I've shot approximately 9000 Summit City 9mm 124gr no lube groove bullets. They shoot fine, with just a little smoke. If you watch for sales, you can get free shipping and 14% off with a double box of 3500.
I ran into this and posted on another forum. The response I received was that they came from loads that had no lead primers, and this was why they were crimped. Greenies saving us again.
Mine was pretty tight at first (4 1/4"). After switching to a steel firing pin and a 12lb recoil spring, it runs great. The factory magazines have been flawless.
I tried .358 when a supplier sent them by mistake. I ordered .356 but figured I would reduce the load and see. They were fine in my Ruger but would not chamber in my Sig. I contacted the supplier, they exchanged and paid shipping.
I have used Unique for years and like it. When things started getting scarce last spring I couldn't find any so I stocked up on Universal. It burns about the same rate and takes a little less to get me there.
