D-1, sorry but your involvement of the bolt threw me. I have checked several M1's but always had the bolt locked back. Maybe it is my semantics but on my M1 the rear of the receiver is where the serial number is. I agree that the bolt lugs are not under a shroud like most bolt actions but they are still at the front. My experience is that most of the M1917 rifles we see were not used very heavily. Some did see service in WW1 but most of the rifles produced were later used for second line troops, drill, training and given to Allies after WW2. Many had replacement barrels from Johnson Automatics, High Standard and RIA/Savage then put into storage. My long winded point is that throat wear is probably much lower than M1's or even Springfields. I know shooters who go through an AR barrel per year shooting competitively. Myself, I doubt I will ever shoot my M1917 enough to warrant a new barrel. Let us know how things pan out.

I have talked to Steve Mathews about his ME TE tool (it is a hobbyist and not the real thing but works just fine)

He never calibrated it to the 1917, but he said the checks he made were close.

As we are not talking small amounts here (relatively speaking) it does not matter if its 1/2 a number off or even a whole number.

they tend to fall in the very good to ok, or off the edge of the map.

My sampling looks like its no more than 1/2 off. Muzzle is identical. Just read at the recess in the crown not the top.

Also the SM ignores the first line (that is zero). We have seen sub zero on a couple rifles. Doesn't mean anything, mfg varation.
