303 H/S gauges

[Simon P]

Border Ballistics Technologies will make them for you, just tell Geoffrey exactly what size of head space gauge you want.

I don't like coin gauges. I've had too many folks send rifles here that were supposedly out of spec when checked with them and when I check again with proper milspec gauges, there's nothing wrong. Of course, we have a saying in the South: "operator failure". I'm guessing that's more the problem than the gauges themselves.

Serious folks should contact BBT as Simon has said and get a real one made.

Apparently BBT will only sell to licensed gunsmiths or dealers, of which I am neither yet. I am hoping this only applies to their reamers and not the headspace gauges, but I'll ask anyway.

I hate to resurrect this thread but for the sake of those who still want a place to get their gauges: Geoff at BBT is the man for the job. Both gauges for what I call reasonable and in good time. I've tried my two nicer guns and both check out (just).

ANYONE wanting Headspace .303 gauges should talk to Geoff.

Hope this puts this whole shebang to rest properly.

I think you will find that .30-40 Krag shares the exact same "Go / No go' gauging of .064" / .074".

Being gauges for rimmed cartridges, they will have short bodies and be thus interchangeable between .303 and .30-40; not only serving those two chamberings, but pretty much any wildcat derived from them.

[Parashooter]

Common US gauges for .303 or .30/40 are .064" Go, .067" No-go, .070" Field. Only the "Go" is useful for inspecting arms in service. The "No-go" is good for installing new barrels and the .070" "Field" is simply useless.

I agree with you. My point was not too clearly stated. The .064 GO gauge can be purchased directly from Forster and Clymer for around $25-$30. It's the same specification as SAAMI. The .074 No-Go is the difficult one to find.

At least at one point, Forster would make an .074" field gauge to order for a nominal fee. Not sure if that is still the case.
