Go/No-Go Gages

bill7007 · November 01, 2002, 18:17

I got my LS from Jen today. That puppy is a tight little sucker..
My question is I removed the firing pin and chambered a live round. Bolt locks up fine. I put my go gauge in and it wont close.
I do still have the extractor in. Will it interfere with a Go gauge closeing the bolt?. Seems like the live round chambers fine and locks up good. Should I remove the extractor and try again?

Yes remove the extractor.

Headspace gauges are not really designed to be chambered like a round; i.e. drawn from a mag, slammed into the chamber under spring pressure, extractor snapped over the "rim". It's a precision instrument and is too fragile for this treatment; you'd probably break the "rim" in quick order.

Partial points for removing the firing pin before your test with live ammunition. I leave it in place during headspacing, however, so as to not allow any potential disturbance in the relationship between bolt and carrier.

[Edited to add that I hadn't thought you'd chambered your GO gauge like a round; certainly you didn't say anything to give that impression. I was just trying to make the point that a headspace gauge is not designed to accept an extractor snapping over it, even though it might withstand the process a number of times; and that trying to take a reading with the extractor still in place will usually affect your measurement, as you discovered. Apologies if I gave the wrong impression.]

The Gauge was not loaded like a round. The upper was off the lower and no spring tension at all. I mearly did the test just like I did when I used the pin gauges. Thumb pressure. Except I really wasn't relishing the thought of taking that pesky extractor off.

At 20 bucks a piece They had better be a PRECSION INSTRUMENT.
I removed the extractor now and all is well!..Guess that extractor was the key.
Thx
Bill
