Re: 338 Lapua Headspace Problem?
I am certainly no expert, learning myself. I would take a hard look at the boltface. My TAC 388 uses a PT&G bolt. Most of my problems stemmed from burrs on the ejector hole and also from burrs under the extractor. When I removed the extractor from the bolt, I noticed a pretty good sized burr sticking up towards the boltface.
I had assumed a custom action would have been accurized. I assumed incorrectly! Nathan dagley did a Phoenix action for a different rifle for me. I hear he sometimes recuts the boltfaces on the PT&G bolts along with other things to get a precision action. Nathan knows these actions inside and out.
