I'm trying to find out if I got a bad batch of Tula primers or if the springs on my guns are too light to reliably detonate hard primers. No exaggeration, about 20-30% of all the rounds I load using Tula small pistol primers do not detonate (light primer strike). I've shooting them through 2 Glock .40s and a CZ-75 .40. I know Tula primers are supposed to be pretty hard but this is ridiculous. This is something that's been going on for months now. I usually don't use them but a friend of mine has a few thousand and I buy some off him sometimes, so these are coming out of the same box of 1000. Has anyone else had this much trouble with Tula primers? I've never had this problem with Federal or CCI.
