Last range session I shot exactly 20 rounds of 300blk subs starting with completely clean internals and it was locked up enough to have to beat it apart (as usual). I used to blame this on rimfire lead fouling but it became clear that it happens just as bad with centerfire. The problem is that fouling cements the monocore core to the outer tube. I can't comprehend a suppressor that I can't shoot just a few rounds through without having to stop and clean it or at least break everything loose. I made sure I had the tube and as far as I could tell the core completely clean of fouling before shooting. Have I damaged mine somehow to cause it to do this or does it just suck?
This last time it was dry but I've tried leaving lube in it to no real effect. I'm almost at the point of just sanding down the OD of the core to give more clearance but I know that will reduce the performance. I've had to beat this thing apart so many times I'm beginning to damage the threads.
