I recently acquired a 1903 Springfield action. Does anybody have dimensions of the chamber & barrel shank. I have drawings showing shank dimensions and thread, but nothing showing internals, that is the angle and depth of the coned area at the breech and the extractor cut.
Is anyone making short chambered barrels for the Springfield?

I don't have the angle of the feed cone, or the extractor dimensions here, and it's raining cats & dogs so I'm not about to go out to the shop right now to get the info, but the barrel shank is 1.040"x10 square threads per inch, .940" dia. to the thread root. Shank is .734" long. Other than replacement military barrels, I am not aware of any short chambered barrels for the Springfield. Unlike Mausers, there's not enough of them being barreled to justify the expense...also the feed cone and extractor locations require proper indexing...

CMP has short chambered 03 and 03A3 barrels made by Criterion a division of Krieger. Click on the link below then go to the "Estore" and click on barrels.

The Clymer cat. lists the feed cone reamers and they are 96°.

Thanks for the information. I was familiar with the Numrich barresl, but not the CMP ones. I am in hopes of finding a sporter though, not a military with the various cuts for sights, etc.

The coned barrel is a "nice to have" situation, not a necessity. A regular squared-off barrel works, if you put a pretty good chamfer at the back to help the bullet nose find the chamber. The coned back of the barrel was mainly to help when dropping a cartridge in during single-loading, with the magazine cutoff engaged. The P-14 Enfield and the M1917 US rifles had the same rear barrel shape, and they work OK with a square-backed rebarrel, also. Once a case slips under the extractor while controlled-round feeding from the magazine, it's almost directly in line with the chamber anyway.
