Chamber Drawings

[montana_charlie]

Does anybody have a link to a site that has a large selection of rifle chamber drawings? I just need basic dimensions...not engineering blueprints.

Specifically, I am in need of dimensions for the 44/90 (BPCR) case, and I don't know (right now) if that is the bottle necked version...or a straight-cased type.

Alternatively, an online source of chamber reamer drawings would be helpful. Clymer's site used to have a bunch, but they are no longer available.

Thanks for taking time to respond, but two things about your suggestion keep it from helping.
First, I don't have an account there, so I can't view any of their stuff.
Second, which part of 44-90 did I misspell?

Isn't it neccessary to be a member of some organization to get anything from the SAAMI site? I have tried to find information there in the past and came up empty.

Do you have a manual, with 44-90 in it, that you could scan and email me?

Selective dyslexia on my part... sorry.

Here's some better data anyway:


.44-90, .44-100, .44-105 Sharps (Necked) and .44-90 Remington

The .44-90 Sharps was introduced in 1873 and discontinued in 1878. All three of these numbers are based on the original .44-90 case; the .44-100 and .44-105 simply represented heavier powder loads in the same cartridge.

The .44-90 used a rimmed, bottleneck case 2 5/8" long. Its base diameter was .517", shoulder diameter .504", and neck diameter .468". Bullet diameter was .446" and COL was 3.30"

This cartridge was more popular as a long range match cartridge than as a hunting cartridge, although it was used for both. Factory loads gave a 520 grain lead bullet a MV of 1270 fps and ME of 1860 ft. lbs.

Very similar, but not quite identical, to the .44-90 Sharps (Necked) is the .44-90 Remington Special. It was designed as a match cartridge for the Remington Rolling Block Creedmoor rifle and was also introduced in 1873.

Its case had a base diameter of .520", a shoulder diameter of .504", and a neck diameter of .466". Case length was 2.44" and COL was 3.08". The correct bullet diameter was .442" rather than the .446" of the Sharps .44-90 cartridge.

Factory loads gave a 550 grain lead bullet a MV of 1250 fps and ME of 1812 ft. lbs. Although primarily a match cartridge, the .44-90 Remington had the accuracy, power and penetration to make it a good bison cartridge.

MC - In my limited library, Howell, Donnelly and Mack I only find reference to 44-90 rem straight, rem necked, 44-90 Sharps and 44-90 Peabody. Is your 44-90 WCF the same as one of those? If so, I can give dimensions of those cases if that would help you.

Actually, the guy with the 44/90 is no longer in need of my assistance, so my quest for information about his cartridge has ended.

My thanks to all who replied.
