What are you doing that you need more oomph than a .45-70?
Typically loaded with powder charge 65-70 grains and a 520-540 grain bullet, it carries up well and hits hard.
If you are going to be a 1000 yard specialist, then you can make a case for a 2 4/10" or 2 7/8". The 3 1/4" is just absurd, I don't know anybody shooting it where score is kept.
You are wasting powder and lead loading a .45-90 with .45-70 ammunition. That was ok before the BPCR revival and it was the only way you could try out Grandpa's Gun, but there is no rhyme or reason in it now with proper brass available. The .30 jump through the longer chamber is not going to do anything good to that soft bullet.
If you want to tone down the longer round, load it with Fg powder and/or a lighter bullet. A lot of silhouette shooters have "chicken loads" for the 200 metre birds.
Me? I shoot .40-65, a 400 grain bullet is a lot more fun than a 500 when you are shooting all day or all weekend. But then I only shoot silhouette and midrange, 500 metres and 600 yards max.
The line count from the 2011 Southeastern Regional combined silhouette and midrange match showed 26 .45-70s and only 22 of all other calibers combined, larger and smaller.
