so i got this forster no go gage....

[goo]

...which all of my garand bolts close on. the number, on the gage is as follows:
2.0547

it engaged the extractor okay and then i closed the bolts.it also extracts okay. i guess i could remove the extractors and try it again but i don't see how it would make much difference.
the garands themselves, which include a CMP special grade springfield, and two h&r correct grades and some cmp service grades i think are basically fine.
maybe i got the wrong kind of no go gage and should of got a field gage. i also got a throat erosion gage and all the rifles is below 3.0.
the special gage which has a new is 1.0.
any inputs would be appreciated.

you need a field gauge. Probably safe, though

Forester gages have had a lot of reports of problems. Get a nice set of Clymers.

2nd. The bolt can close on a go, no-go and be perfectly safe to shoot. If the bolt closes on a field reject gage, then excessive headspace exists and the rifle needs to be rebarreled (or find a longer bolt).

When a barrel is new, it is short chambered. The barrel is mounted and then finished reamed so the bolt closes on the go gage (indicating min headspace). The bolt should not close on the no-go gage if the smith has done his job right.

For a used barrel, just make sure the bolt closes on a go gage (min headspace) and does not close on a field gage (excessive headspace).

Just to be clear you need the rifle field striped. The bolt should be striped. The bolt face and chamber is clean and dry. You put the striped bolt in the recvr., insert the gage in the chamber and very lightly close the bolt by hand. When you feel resistance stop. The no-go should not have the bolt lug drop to the recvr. This is still OK if the field gage does not close. No-go is just a check gage when chambering the barrel.

You are not to have rifle assembled with op-rod and spring. These gages are all used by "feel" only. Some gages have cut-outs for the ejector so that it can be used with the bolt assembled. Best to strip and get a good feel on when it hits/stops with very light finger pressure.
