Of course that barrel could be returned to a ‘kinda military’ condition. But unless you have a $100 or so, you are willing to put into an appearance thing,,, you are going to have to do...
Well, Williams is wrong (as are many people) on one count, the big problem with the Low Number Receivers was not the heat treatment,,, it was the FORGING.
Hunk of steel heated, then forged into...

From ViShooters site; 01 Jan 1919 started with #1055092 and 01 Jan 1920 started with #1162501.
So your receiver was serial numbered in 1919, my guess is in the first quarter and the barrel...

Perhaps you have a USMC sight cover, they are higher and are meant to be left in place while firing, if the shooter chooses to do so. In other words the rifle can be fired with or...
No Chuck. Rock Island never made barrels for the M1917, they installed barrels made by others, (Remington blanks, Savage machining ) and stamped RI on them but never made barrels for the M1917. ...
Chuck is right that two groove barrel shoot very well, some two grooves shoot better than four grooves and visa versa. I have heard that after four to five thousand rounds the grouping ability of...
During 1967-68, as the Koreans were being re-equipped with M16/ M60s, the Koreans proposed to give to the ARVNs their M1/2 Carbines , M1 Rifles, BARs & Browning MGs. (and I believe had already...

Benny’s question is about the screw that holds the ‘BAND, bayonet stud’ to the end of the stock, and yes I was also confused at first. That screw is not staked, (it maybe...

According to Ordnance Drawing A153074 (changed to 5153074 in 1949) “SCREW, Lower Band and SCREW, Stacking Swivel Band” dated May 1, 1942, thread size is “.130 (NO.10) 32NF - 2” or 10x32. ...

There are two GI Breech Bore (erosion) gages with drawing #C3940. One has nine spaces between the rejection line for machine gun barrels and the rejection line for rifle barrels, the other...

When specifications are drawn up for a cartridge, there are dimensions for this cartridges and there are tolerances for these dimensions, a minimum and a maximum. The US...
IF that barrel you supplied to the gunsmith was a ‘new’ barrel and was tightened until the index marks were aligned (one on the receiver and one on the barrel) the bolt should not have closed on a GO...

‘Short Chamber’ The barrel is not fully chambered during manufacture, so that when fitted to a receiver, index marks lined up, the bolt will not close on a GO gage, so that the chamber...
From the few reports I have read by people who actually have the rifle, it is a good serviceable rifle.
The Chinese screwed up and the directions in which the windage and elevation knobs should...
Interesting,,,,,, that barrel might not be as ‘new’ as the seller thought.
But rifle is safe to shoot, so all is good.
Do not put too much into what the woman at the shop says but just smile...

Some more second guessing…
The case on the glass is the “if it has excessive headspace the primer will back out enough to cause the case to wobble” test. I don’t trust it at all...
The gent doing the shooting is so ugly he must a Brit.;)
Out of curiosity,, what is his full name and is it ever used? Like on legal papers, birth, divorce???

Ive slugged a number of the WWI barrels,, most were in the 0.309” range. A very few were 0.310”.
If I remember correctly, the Winchester barrels were the tightest, but always more than...
No Steve, firing grenades off a M1903 did not ‘immediately’ crack a stock, I’ve done it enough and did not crack any stocks,, pined or bolted. I fired all mine off my shoulder, as it should be...

NO!!!!!!,,,,,,, it was NOT the heat treatment, it was the forging.
During heat treatment the receivers were covered in the carbon adding compound, they could not be seen during the...

According to http://www.vishooter.net your receiver was serialized in 1934. Old Guns’ list has problems, Poyer is mostly a waste of paper, drawing are OK. Springfield did not...

Thanks I will try that.
I had one of those 7.62x39" Rugers, as far as I know, I never fired 0.308" dia bullets thru it.

I figure there must have been some type of study,, given the warnings people are always writing about firing oversize bullets.
I had read Ackley’s books before I did that little...
Does any one know of any test/experiment that have been done to see what the increase in pressure is,, with each increment of increase in the neck and bullet diameter with everything else staying the...
