Anyone having problems with PTG bolts?
I finished another .260 build tonight and went out back to see how she shoots. This rifle was built with a PTG bolt and was fitted pretty tight. The lugs were machined for 2-3 thou play at the bolt handle. She closes fine on the go gauge but not on the gauge plus 2 thou worth of tape on the base of the gauge itself. Chamber is good, bolt nose clearance is good, and the machining of the lugs is good. Receiver was trued before barreling.
I had a very difficult time chambering rounds. It acted like the shoulder on the case wasn’t set back far enough but the problem ended up being the extractor. I ordered this bolt with the Remy extractor instead of the mini 16 (my first mistake). What is going on is that there is very little to no play so it doesn’t snap over the case rim. It cuts/rolls the edge of the rim instead. It’s not the extractor; I’ve tried 3 of them. It almost seems like the groove in the bolt head wasn’t cut deep enough to allow the extractor to move.
Has anyone else had this particular problem?
I’ll be calling PTG tomorrow but wondered if anyone else is having these issues. I suspect they’ll want to see it but we’ll know for sure tomorrow. I’ll gladly send it back but it kind of sucks that a new rifle is going to sit until we get this cleared up. Guess that'll give me an excuse to get started on the Swift.
Hopefully they’ll help me get this sorted out and then tell me when I can expect the bolt for a waiting .223AI build. That’s been ordered since last fall.
