I’ve been trying to shoot 330-345. I’m pretty sure you’re right, been shooting too hot. I’m going to store to get new orings tomorrow. Thx PVL

New to making my own soft plastics and have not been able to find this particular issue discussed (though I did not dig deep). My capsule oring gets coated with plastic and sucked back into the injector tube. What am I doing wrong? Obviously, I then have to waste time removing all the stuck plastic. I've been lubing both with worm oil and preheating the injector and molds prior to shooting. No problem with the plunger oring. Any helpful hints, tricks, suggestions would be greatly appreciated. Thx PVL
