I've been watching these for awhile. Made in Argentina. I think the first batches that showed up in the US had QC problems which were resolved. All the latest I read about them is pretty good.
Complaints have been that some striker fired guns would not ignite them. I ordered 7000 from Republic Ammo for $47.50/1000. Got them today after ordering Thur night. Fedex delivery and packed well.
I loaded up 15 9mms just to try them. They seat similar to the last Ginex I'm finishing. Maybe a bit easier. Lee Pro1000 press. I even seated one in a military case I cut the crimp out of and it was fine. My Ginex have been particularly hard to seat in these and sometimes end up squashed flat. The SA seated easy and kept its' rounded edges.
Fired them out of my CZ SP01 with lighter spring kit, PSA Dagger striker fired, and FM AR9 with 3.5lb trigger spring kit.
All fired just fine. Primer indentations are similar to Ginex. Top is SA, bott Ginex.
I think these are going to work just fine for me. I was worried about the striker fired pistol as well as the AR since the trigger spring kit had a warning about igniting harder primers. I'll keep updating this thread as I use more of these.
