Long Actions/Short Cartridges

Can a rifle such as a Springfield 1903 or a Remington Model 721 be chambered for .250 Savage? Does it have to be blocked behind the ctg?

Several years ago I did a 22-243 on a LA Rem 700 and it required a 'block' at the rear of the mag box and a 'custom' follower did the trick. Fed like poop through a goose. I think you'd be facing the same situation if you use a 1903 or a Rem 721 for the .250 Savage. An alturnitive cartride would be the .257 Roberts. No mag/follower work required with that one on a LA.

owlhoot,

We've been doing it since 1988 for the M-24 Sniper Weapon System:

The M24 SWS has the "long action" bolt version of the Remington 700 receiver but is chambered for the 7.62×51mm NATO "short action" cartridge that has an overall length of 2.750 inches (69.85 mm). The "long action" allows the rifle to be re-configured for dimensionally larger cartridges up to 3.340 inches (84.84 mm) in overall length.

Depending on time and dollars, many of these projects can be mastered with some ingenuity and knowledge.

Regards.

.250 Savage is shorter than a .243 or .308 Winchester and has significant more taper in the case.


Good luck

DOLLARS is what usually stops it! Seems there are many more looking for "drop-in", than are willing to pay for a gunsmiths' knowledge. The OP asks about two different actions, one a push feed (Rem721) and the other, controlled round feed (the 1903). If you can raise the cartridge 'till it's 'hooked' under the extractor, you now have 'control of the cartridge' for feeding into the chamber. The coned breech of the 1903 helps here, as it acts like a funnel for the cartridge to 'flow' into the chamber. The push feed (the 721) doesn't have a Mauser like extractor. A portion of the loaded cartridge needs to be 'on its way' into the chamber before the feed rails let go of it (the cartridge). If it's not "on its way into the chamber", it'll just flop around on top of the follower/cartrides in the magazine where the 'machinery' no longer has any 'control' over where that cartridge is going. Sure, it'll go forward, because the bolt is pushing it. There's a good chance the bullet tip will hang-up somwhere in this scenario. My best 'guess' would be the 1903 with its controlled round feed and coned breech. It'd still require some 'work'.
