44-90 Sharps Necked 2 7/16 Cartridge

HELP !!!!

Measured the chamber on my new to me Ballard 44-77 Sharps Bottle Neck (SBN) and came up with a case length that was longer than the 44-77 SBN. There are no cartridge stampings on the barrel. I have some cerrosafe on it's way to me and will do a chamber cast as soon as it gets here.

My measurement of case length came up at 2.460 inches in length as compared to 2.25 for the 44-77 SBN. All other measurements are close to both.

Can some one get me the 44-90 SBN 2 7/16 and 2 5/8 distance from the rim to shoulder length. As none of my sources have this information.

TNKS !!!

Mine is 2.547" from the face of the rim.
2.652 from the back.

I guess there are a couple of different lengths for the 44-90 SBN. I have an original Sharps 44-90 SBN (long variety?). The junction between the case body and the shoulder is a slight radius so that measurement is best guesstimate at center of radius. These measurements are from a case that has been fired a few times in my chamber.

Total case length- 2.610
Base (bolt face) to shoulder junction- 1.940
Neck from mouth to junction with shoulder- .578
Rim thickness- .085

Maybe apples and oranges but another bit of info won't hurt.

Reslugged the barrel today, this time with an expanded .446 bullet, bore is .443 and grove is .451.

The guy I got the gun from had good luck using .446 grease grove bullets made 30-1.

He was using 43 Spanish brass expanded out to .446. Got the brass with the gun.

Can't wait to the cerrosafe gets here. 'cause there is now 3 posibilities:

44-77 Sharps BN 44-90 Sharps 2 7/16 (2.46), the right length and the 44-90 Remington Special Necked also the right length

You asked for the 44 bn sharps, there is a difference between the two.

The Rem .44-90 bn 2.44 used a shorter case than the Sharps .44-2-5/8 or .44-100 it was a 2.63.
The Rem special necked used a .442 diameter patched bullet as well as the .44-90 rem straight did.
Sharps used a .446
The chamber drawing above I had cut from a original cast from a 1877 Sharps Creedmoor. The bore diameter and groove diameter I changed on that reamer to fit the .438 bore .446 groove that Shiloh now makes there barrels.
.405 is right with the shoulder having a slight radius. You can see that in the specks on the drawing.

WELL !!!! The Cerrosafe arrived today and just had to do a chamber cast. Doing a chamber cast removes all doubt !

It is confirmed, it is a 44-77 SBN with free bore for the paper patched bullet. Without the chamber cast it appeared optically using a caliper, that the cartridge length was actually longer.

Anyway, tomorrow, the Ballard will be making smoke !!

Thanks for all of your inputs.

Found it !!!
44-90 SBN 2 7/16 is the same case as the 44-77 SBN with the bullet seated out to the same OAL as the standard 44-90 SBN. It did not last very long due to the bullet being held in by 1/4 to 3/16 of an inch depending on which bullet was used.

TNKS for all your help !
