![]() ![]() Springfield 1903 Serial Number RangeIn the Springfield rifle the head of the cartridge case projects out of the rear end of the chamber a distance of from. Such rifles should be regarded as collector’s items, not “shooters”.One thing made evident by these tests is the fact that the weakest feature of most modern military actions is the cartridge case itself. In addition, any bolt marked “N.S.” (for nickel steel) can be safely regarded as “high number” if obtained directly from CMP (beware of re-marked fakes).CMP DOES NOT RECOMMEND FIRING ANY SPRINGFIELD RIFLE WITH A ”LOW NUMBER” RECEIVER. If the brass doesn't fail then there is no problem. That is the main reason why we never, or at least hardly ever, hear of a burst Krag receiver.The problem with low number M1903s is the combination of the chamber design and a receiver in some that is brittle and weak. The case enters the chamber right up to the rim, and there is little chance for the cartridge to fail at the head. Garand took great pains to eliminate this source of weakness by arranging the rear end of the chamber and the front end of the bolt so that the metal of the cartridge case is surrounded right down to the extractor groove by the chamber walls.The Krag, which uses a rimmed case, does not have this weakness. If the receiver is weak or brittle, it may be fractured if it is strong, then the extractor may be blown off, the magazine well may be bulged, the stock may be splintered, and other damage may be done.In the design of the U.S. This is the weak point of the M 1903 Springfield, the M 1917 Enfield, the M 98 Mauser, and other high powered rifles using rimless cartridges.When very high pressures are encountered, the brass wall either spreads or blows out, and the gas under high pressure gets loose and wrecks things. Pokemon fire red 5000 exp cheatSo you are relying on the strength of that. The receiver will most likely shatter because it is weak and brittle. But if you have a brass failure there is no safety margin. But you must handload and be very selective about the brass you use. If the brass is sound, a full-power load isn't going to rupture it, so you might as well shoot full-powered loads. Such rifles should be regarded as collector’s items, not “shooters”.Reduced power loads and cast bullets aren't going to protect you if the brass fails. After a certain number of firings stop using that brass for that low number M1903 and use it in other rifles.Since high number M1903s are easy to find (I've bought two within the past month, one for $300 and one for $800) in my opinion there is no reason to take even the small increased risk of shooting a low number M1903. After the initial full-length resizing use that brass only in that low number M1903 and neck resize only. Using once-fired brass (fired in a different rifle) means the brass has been "proofed". There is a tiny chance brand-new brass including that in factory ammo could have a manufacturing flaw.
