Reloading for Springfield 1903A3

[John Kepler]

"Exception, the 30/06 chamber and the M1 Garand" The information is available, I acquired a gage that measured .000005", I assumed they, in the old days made the gage for future use.

The information was made available before the Internet,

What in hell does having an alleged sub-micron measuring device have to do with machining something to those tolerances???? I know it's hard, but try to compare apples to apples, OK?

John Kepler, that was rude, You are arguing with me? The dimensions of the Garand chamber has been published, before the Internet. If you do not have this information available please ask me to provide, again, all of this information was available before the Internet.

Forgive, there are those that work in the claim department, they claim the M1 Garand chamber is generous, they do not know how generous, I can only guess, they read it on the Internet.

Yet another person making noise like an engineer without the slightest clue about what engineering is! NO ONE making an engineering drawing for a production product is going to spec a fractional thousandth dimension, not then, not now! In this case, it's even more absurd......there is an expressed production tolerance protocol that in this case involves ranges in the double-digits! NONE of my spec sheets on the chamber identify ANY fractional thousandth as a nominal dimension.....you either have an erroneous document, or have misplaced a decimal point. OH.....FWIW, I HAVE the Garand chamber specs, have had them likely longer than you have, and certainly got them "before the Internet", whatever the hell that signifies, but then you are apparently one weird Dude!

You don't want "rude", don't talk nonsense masquerading as true data!

Excuse me for the interruption.... but this thread is about 30.06 loads for the bolt action 1903A3, not about the Garand.

Closes on the NO-GO gauge
and doesn't on the Field, bolt comes over maybe 1/4 of the way. I have special headspace
gauges and it will close on a 2.054 gauge and again not the field.

I don't know what "special headspace gauges" but and I wouldn't hesitate to fire a rifle that would not take a "field" gauge but fails the "no go" gauge... with factory ammunition.

Personally I have 3 1903/A3 rifles and I use different loads for each and neck size only. If I had a headspace problem and the barrel was still good, I would probably have the barrel set back 1 thread and re chambered. (Some people will say that is a dangerous practice but I have never had a problem with any of the rifles modified that way + a very good gunsmith that did the work tells me he has done the job hundreds of times.)

If I were concerned as you seem to be then by all means either use factory rounds or reduce your loads for that rifle.
