Savage11006 Posted March 5, 2022 Report Share Posted March 5, 2022 Ok. I got my go no go gauges in yesterday and decided to check my headspace. I couldn't get the bolt to turn on the go guage. Toolcraft bcg with high pressure bolt and double ejectors. Barrel is not installed on the upper. I don't have an extra bolt or anyone that could lend one to check. Is there anything to do without having to buy another bolt? Quote Link to comment Share on other sites More sharing options...
shooterrex Posted March 5, 2022 Report Share Posted March 5, 2022 Did you remove the ejectors and extractor from the bolt? Quote Link to comment Share on other sites More sharing options...

Savage11006 Posted March 6, 2022 Author Report Share Posted March 6, 2022 Well i tried the factory round and still no luck. I'm wondering what the difference is between a regular bolt and the high pressure one Quote Link to comment Share on other sites More sharing options...

Savage11006 Posted March 6, 2022 Author Report Share Posted March 6, 2022 Ok, so nothing in the actual dimensions of the bolt itself. Thanks Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 6, 2022 Report Share Posted March 6, 2022 ^^^ Correct. Quote Link to comment Share on other sites More sharing options...
MaineMan2 Posted March 8, 2022 Report Share Posted March 8, 2022 I had the same problem with an Aero Precision bolt and Fulton Armory barrel (Criterion blank). Fulton Armory had me send bolt and barrel to them. They said that the bolt would close on their GO gauge but still reamed approximately 1000th (according to them) more off the chamber and polished it again. Bolt now closes on my Forster GO GAUGE. Please note - this barrel is described as “match quality”. IOW the chamber is deliberately tight and I had tolerance stacking. Also, FA specifically stated that they only use Forster headspace gauges for whatever that’s worth. Also DO NOT USE CARTRIDGE to check headspace. That’s just wrong. Cartridge dimensions are deliberately spec’d slightly smaller than chambers. Think about it - they need to be. Quote Link to comment Share on other sites More sharing options...
Savage11006 Posted March 8, 2022 Author Report Share Posted March 8, 2022 I sent Wilson an email earlier, just waiting to hear back. I know if i put the bolt in without the guage it doesn't seem that there's much clearance to me so maybe it's a similar issue as yours. My guages are clymer. I don't know if those are any good or not. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 8, 2022 Report Share Posted March 8, 2022 All gauges are good - to what the manufacturer specs, and they make them in accordance with cartridge specs. But there are tolerances, even in the case dimension drawings, on every cartridge. It all comes down to what gauges your barrel manufacturer uses, when setting up their chambers for Go and No-Go, and how tight they set their headspace for those gauges. Some gauges will give you a No-Go on a Go gauge, just based on that. Quote Link to comment Share on other sites More sharing options...
Savage11006 Posted March 8, 2022 Author Report Share Posted March 8, 2022 Gotcha, ok! Thanks again Quote Link to comment Share on other sites More sharing options...
Savage11006 Posted March 9, 2022 Author Report Share Posted March 9, 2022 Well here's the reply i got back from Wilson combat The go gauge will not work with our bolts as the tolerances we have are too tight for it to work. It may be the same way with the toolcraft BCG. Apologies, but I'm not familiar enough with toolcraft to say for sure.
