When you get to shooting would you inspect the cases and look for a bulge where the extractor matches up. Mine leaves a small bulge right there and I am thinking about sending some fired cases in to TC and get their opinion. Shot it around 600 times so far no problems and steller accuracy so I hate to send the barrel back but I don't want to deal with a gas escape either.
If yours has an issue then so does mine. All the cases from rounds fired this morning have that little bulge. I'm not gonna sweat it.
Did pretty well with both SV and RWS SSHP, and to very nearly the same POI. Thinking about a scope with more Xs, though the little Weaver works perfectly.
