    I just recently bought a "safe Queen" Remington 1903 A3, Arsenal rebuild. It looks like someone bought it after WW2 and put it in a closet. looks like it has not been fired at all. The problem I have is that when chambering M2 Ball ammo it is kind of tight. Also the distance between the rear of the safety lug and the receiver is about 1/16 of an inch. Is that normal? Anybody have any thoughts?
    The first suggestion is "Short Chamber"

    Nothing could be further from the truth. The first 03 rifle had a straight handle,, then came the slightly bent back handle. The early 03 bolts fit the receiver with a few thousandths clearance in front of the rear receiver ring and the exposed 3 safety lug. After Remington etc., started building the Remington 03 and the 03A3 etc., the gap between the rear sight bridge and safety lug widened. Then came all of the replacement bolts, all had the wide gap.

    Because I am the only one checking the length of the chamber with a feeler gage and have a concept of zero the gap behind the 3rd lug is meaningless to most. I measure the length of the chamber with a feeler gage. the third lug eliminated a limiter for forwarded bolt movement.

    Hind sight, the length of the chamber from the shoulder to the bolt face could have been tracked if anyone had noticed, recorded and kept track of the gap.
