45-70 in a 45-90
Would you expect any problems shooting 45-70 cartridges in a single shot rifle chambered for 45-90? How about excessive leading? thanks

Hello,
No, I would not expect and serious problems... you will experience the same issues as you would by shooting .38 Specials in a .357 Magnum, or 22 Shorts in a 22 Long rifle chamber. That said, if you shoot the shorter cartridges, you will need to thoroughly clean the chamber before you shoot the longer cartridges.
On other thing to note concerning shooting the 45-70 in a 45-90 chambered gun, is that the factory rifling twist rate is different for the two cartridges. If you shoot the 405-grain bullet (or heavier) 45-70 load, you should not expect good long-range accuracy in the 45-90 barrel. The 45-90 has a twist rate that is optimum for a 300-grain bullet.0 -
It won't blow up, if that is what you worry about.
Accuracy may not be great with the bullet jumping .30", this is a rifle, not a .357 revolver loaded with .38s for 50 yards at most.
Shooting .45-70s in a .45-90 is something you can do just to say you shot Grandpa's Rifle or hunt from a stand at short ranges. If you want more out of the gun, .45-90 brass is available for the handloader and ammunition is available, although more expensive.
Kirk Bryan, owner of Shiloh Sharps, said he saw an original Sharps that had been shot a LOT with .45-70s in a longer chamber. It was badly eroded or more likely corroded under fouling.
Surely you won't be doing that.0 -
I had a 45-90 Model 86 deluxe 2/3 mag rifle (39,XXX) that outshot three new condition 45-70 trapdoor rifles. All used 45-70-450 blue label
Govt, black powder ammo at a 100 yard range.
This was in about 1951-52 when excellent Trapdoors and surplus 45-70 ammo was cheap. Others repeated the tests demonstrating the Winchester was more accurate than the Springfields even though the 45-90 twist was for 300 gr bullets and the Springfields were cut for 450 & 500gr bullets.0
