Re-chamber .45-90 to .45-120?

Hello all,

Here's an idea I'm contemplating:

Is it possible, or indeed, advisable, to re-chamber a 1874 Sharps from .45-90 to .45-120?

Any feedback from any of you who might have tried something like this will be greatly appreciated.

I see no problem doing that, but why stop there, do it in 45-120- 3.5 or something like that. Cost would be the same, I did something like that but on a rolling block several years ago. You just have it rechambered by someone like Montana rifleman or any one with a lathe and the correct reamer. thnx

What are you going to use the rifle for? Long range BP shooting? I would not recomend doing that if you`r trying to get the best grouping with less work. Going from 90 to 120 you`ll get a lot more fouling in your bore, and you wount gain that much speed. Im shooting 45-90 at the long range BP competitions. 600 meters that is. Going for the 1000 meter range soon. At 600 meters the 45-70 perform very well too. BUT, for the hell of it the 120 is pure fun.

Holy smoke,.... now I see that this thread is old old old... Forget about the whole thing......
