Cholla Posted December 13, 2021 Share Posted December 13, 2021 I looked at an auction for a Sharps rifle in which the seller states that it is chambered for .45-70 paper patch. I thought (I have never done paper-patching) that it is the brass and bullet that are altered, not the chamber of the gun. I have tried reading about what the chamber difference would be but have come up short. Please limit you responses to an eighth-grade reading level and easy to understand concepts.

Buckshot Sheridan Posted December 13, 2021 Share Posted December 13, 2021 Some chambers are cut that are intended for nothing other than paper patch. In there there is really no throat or lead into the rifling, it is full rifling directly at the case mouth. This is due to using a paper patch combination that is at or just a few thousandths under bore diameter. A grease groove bullet at the typical groove diameter simply won’t chamber. If using a paper patch combo at bore diameter it is depending on the bullet upsetting into the rifling when the cartridge is fired, and as such requires using real black powder, smokeless or the substitutes don’t give the required pressure curve to reliably get to job done. I had my 50-90 built with one of these chambers. Link to comment Share on other sites More sharing options...

Sedalia Dave Posted December 13, 2021 Share Posted December 13, 2021 Did some reading and it appears that there are a lot of chamber options. Here are a couple of links that may be helpful. Unfortunately I am afraid that they will not tell you much about the chamber in the rifle you are considering as there appear to be several different possible chamber configurations. http://www.shilohsharps.com/forums/viewtopic.php?t=27860&force_isolation=true http://www.shilohsharps.com/forums/viewtopic.php?t=27860&force_isolation=true http://boulderriverfoundry.com/forums/viewtopic.php?t=8820&force_isolation=true https://castboolits.gunloads.com/showthread.php?81563-Paper-Patch-Chamber&force_isolation=true Link to comment Share on other sites More sharing options...
Snakebite Posted December 13, 2021 Share Posted December 13, 2021 Seems there is always something that someone comes up with that claims to make this or that better. I'm sure not prepared to say that none of them work. Maybe a 7 degree lead in to the chamber is the Cat's @$$ for shooting Paper Patch Bullets.... but I doubt that it is going to make Tinker's Damn in this game.

Horace Patootie, SASS #35798 Posted December 13, 2021 Share Posted December 13, 2021 Years ago, I bought a Rolling Block that was advertised as 50 Sharps. I was told 50-90. Bought all of the dies and components. When I checked the chamber, I figured out that it was 50-140. Returned and resupplied my "stuff". To check the chamber, I trimmed the case to fit, then loosely inserted a bullet to determine what OAL should be. Chambered that and determined OAL. Had to use a long bullet at 685 grains. Cartridge OAL was 4 inches. Far left is 50-140, third from left is 45-70. Horace Link to comment Share on other sites More sharing options...
Desert Pete SASS #42168 Posted December 13, 2021 Share Posted December 13, 2021 See if you can find, “The Paper Jacket” by Paul Matthews. It will tell you more than you ever want to know about paper patching. Link to comment Share on other sites More sharing options...
