Aggie's thread got me thinking. Say a fellah had a .45-90...can you safely shoot .45-70 out of it? I wouldnt expect great accuracy or anything. Just wondering if its possible.

Yes but if I had a .45/90 I'd much prefer to get my hands on some .45/90 brass.

Your case mouth will expand at least .005 more than it should, and that is if you have high side 45-70 ammo and match 45-90 chambers.
I would expect that low pressure loads won't seal up well, and will foul your chamber up pretty fast.
Safety might depend on your chamber - does it have a sharp transition from the end of the case to the throat, or is it tapered?
Your bullet would have to be seated pretty far out to go into the throat straight. .300 or more of full diameter bullet outside of the case.
Starline has the brass, and you definitely get all you pay for and then some with those guys. I have 1K of their 45-100 cases for some of my projects.
A major reason I picked the 45-100 was the availability of starline brass. (and standard price dies)

Assuming you're not shooting black powder, is that any advantage to going longer than .45-70?
(I've punched two .45-70's out to .45-90 and in both instances, eventually I went full circle and was sorry I did.)

Starline has the 45-90 brass in stock as of yesterday.

yes, you can, but if you are loading your own and cant find 45/90 brass, you can seat the bullet out further.......works better and should feed better in a repeater.

To answer the original question: Yes you can, in a pinch, but I wouldn't make a habit of doing so. I have a 26" #1-s-C in 45-70 that I thought about punching out, but the top end gain is marginal, and I learned that it takes more powder in the 45-90 to match a 45-70's velocity in any load. |

Many thanks all. This was not a plan...this was was just an inquiry and as expected I got some great input.
