303 go/no go gauges?

[Steppenwolf]

Does anyone know where a fellow could buy 303 brit go/no go gauges? I tried google but only Midway came up.

Brownells sells go-no go gauges for all calibers and shipping isn't a problem

Also there's one member here who sells a few tools for Enfields, including a no-go gauge (got one from him); can't remember the exact CGN name though, darn! Try doing a search in the EE section, I'm sure it's still in there,

I think it was Gairlochian....correct spelling???

A go gauge is it'll chamber a safe, dummy round of .303 ammunition without forcing the bolt closed. Then you should get a Field gauge. It is indeed Gairlochian that makes a repro .074" military Field gauge.

I have both one of his and a SAAMI spec .070" Forster gauge I got from ebay. So far every rifle I've checked has passed with SAAMI, which means it's tighter than the military spec.

Yes, that is him. He hooked me up with a no-go gauge, and a front sight tool. Good to go, send him a PM

Thanks guys, I would much rather spend me money on Gunnutz.

Funny, I was thinking about these gauges and where I might get one just the other day.

"...A go gauge is it'll chamber a safe..." No it isn't. A cartridge tells you nothing about headspace. Mind you, you really only need a 'Go' if you're installing a barrel. Otherwise a 'No-Go' and a 'Field' is all you need to check headspace.

I understand 'go' and 'no go'. What's a field gauge?

 

[GAIRLOCHIAN]

I have these gages F/S.Search for GAIRLOCHIAN on EX of Other Stuff for pics.
Headspace for 303 is .064 min to .074 max.My gages measure .074 (Field) but can supply a GO gage measuring .063.

.303 Brit is an interesting cartridge to guage; as it is rimmed, the gage measures only the rim clearance, what it does not tell you is the size or condition of the chamber or throat. The best choice is to get a real gunsmith to have a look into it. Some of the stuff floating around on the market will pass a head space check, but separate brand new cases every time.

Agreed. My 1950 Long Branch has such a nice, tight chamber that the brass shoulder barely expands. There are old SMLE's where the shoulder moves forward quite a bit on firing...a Ross rifle that had the chamber reamed will produce strange oversize brass...but the headspace is fine, it's really only measuring the dimension involving the rim thickness of the case.

Brownells gages are SAMMI standard which is tighter than the British. So they could fail a rifle that would pass with a British gage. Go with the .074
