    I just received my service grade Garand from CMP. The paperwork shows a muzzle reading of 2 and a throat reading of 2.
    What do the readings mean?

    Means its new to like new condition. Never fired military barrels gauge 0-2 in new condition. 0 being the tightest dimension.

    just note that it doesnt mean it hasnt been used or fired a lot it could have started life at 0 or 1 and been shot enough to erode it to a 2. its just hard to tell when dealing with surplus. you would have to have someone with a barrel scope take a look at the throat and rifling near the muzzle for signs of pitting and wear to determine its true status.

    gaging only gives you a rough guestimate as to the condition of the barrel. kinda like looking at a carbody and interior then trying to guess the state of the engine and transmission. its a good indicator but not a tell all.

    gauges

    the 2 means your muzzle diameter is 301 land to land, wich is little to no wear.
    I got one back in 2000 that gauged 0 and miked at .299
    the same is true for the throat reading. having 2's on both ends means your rifle has had Depot level rebuild on it or possibly arsenal rebuild.

    Really? My '03 and '17 must be in pretty good condition, they both have a ME of 1.5

    I have one that registers from zero to nine in oo1 increments and have mic'd each segment. I don't have one that registers in.5 increments though.
    but your readings indicate a less fired weapon. does the conition of the finish equal to condition of the bore?(is it lees worn?)if not you may have a rebarreled gun could be depot or arnsenal level I had a greek return that swallowed my gauge so I put a Crterion barrel on it that was .299. shot 10 reing at 200 and 300 yards

    I think the barrels are original.... The '03 has a barrel date of 1933 and the '17 is 1918

    souunds to me if they were a less fired pair of guns. I inherited a Remington 1903-A3 from my F-I-L that had never been issued or fired. the gun was as it was made in 1943 parkerized finish except the bolt and it was blued and showed no marks of ever have been operated. the stock had never had the oil finish on it. Had a dealer offer me a ton for it had to let it go, as I don't hang on walls I shoot them. good sgotting
