Sharps BN/SS

No.

Depending on age, there were some oddball .40-70 BN clones adjusted to be formed from .45-70 (2.1") brass before there was enough interest to bring .45-90/2.4" length cases back.

So there is the original .40-70 SBN, a .40-70 BN 2.1, and a .40-70 Gov't.

What are the actual markings on the barrel?
 
OK.
You have one of the short versions meant to be made out of .45-70 brass, NOT an original 2.25" .40-70 SBN chamber.

The other is the .40-70 Government.

One has a long neck and short body, one has a short neck and long body and I don't know which is which. Call Kurt or Belinda at Shiloh and get them to tell you what you need in the way of dies and brass.

(I found on another board:
.40 2 4/10 (40-70BN)
.40 2 1/10 (same powder chamber size as above but with a shorter neck)
.40 2 1/10 Govt (same neck size as 40-70BN but with a smaller powder capacity)
But I would still call and be sure.)

Thanks so much for your help, especially your time. I will contact the Shiloh people and pass on to you what they say. thanks again.
 
I have a Shiloh Sharps 40-70 BN 2 1/10. Barrel marking says, .40 cal. 2 1/10. I use 45-70 brass untrimmed and necked down. Once fire formed the neck is about 7/16" long. I bought my dies from CH 4D.

Thanks for the information, I will look into the dies. If you don't mind, would you share some loading info such as bullet weight, powder, etc. Working on a major learning curve here so I would appreciate any and all information. Thanks again.
 
I have been shooting a 400gr lead cast bullet .408 diameter by Montana Precision Swaging that I have been buying from Cabelas but I bought a bullet mold to start casting my own since I cast for my 45-70. I am also going to increase my bullet diameter to .409 or .410 as I believe the .408 are a bit small in diameter. I shoot 60 gr. by volume of Goex cartridge black powder. When I seat the bullet I seat it to the bottom of the last grease ring. In other words leave the last grease ring fully exposed above the end of the case. That is so the bullet when chambered will just touch the riflings in the barrel. That will also compress the black powder charge about 1/4". After charging with the black powder I also place a paper disc the proper diameter, cut from half gallon milk cartons, between the powder and the bullet before seating the bullet.

I have not used modern powder because I believe these guns shoot better with black powder and they are easy to clean. I have two 45-70's and a 40-70 and I shoot black powder with them all. I shot a little years ago with modern powder when I got my first one but they seemed to kick harder and to foul the barrel with lead more than with black powder. I also do not think they were as accurate with modern over black.

Anyway, I hope that helps you some.

P.S. I think Montana Bullet Works has a large selection of cast bullets to choose from. I have been thinking of buying some from them. I will probably get something around 400gr. and .409-.410 in diameter. Might also try something in the 385gr. range.

I load .40-65 with Swiss 1 1/2 and a Montana Bullet Works Snover design at 408 grains and .411" diameter. That seems large for a Badger barrel with nominal .408" groove, but apparently the Browning throat is a bit large and a .410" is better than a .409" and a .411" is better than either.

Note that Montana Bullet Works and Montana Precision Swaging are not the same outfit. I have tried both and prefer the former.
