Hard to find any loading data as too how much pressure it can stand...

the 32" barrel offers no advantage other than a longer iron sight plane and may cause a decrease of maximum velocity potential depending on the powder and primer combination selected.
With modern powders, the 32" barrel offers no advantage other than a longer iron sight plane and may cause a decrease of maximum velocity potential depending on the powder and primer combination selected.
Stick with middle of the load data sheet stuff listed for the 1886 Winchester and the rifle should last a very long time.

I actually shot mine today. I love it. Light cast loads are a pleasure to shoot and quiet too. The best thing I ever did was add a smith enterprises rear sight. 45-70 is a very versatile cartridge. I started out loading the hot and heavy stuff but now I shoot 350 grain cast bullets over a light charge of trail boss. It's more quiet than a 22.

The 45-70 is a straight case. This means that the bore size is very near the interior case size. This means that the pressure drops quickly as the bullet goes down the bore. You are not going to see the same sort of velocity increases with longer barrels that you would see on a cartridge that has a large case to bore ratio, such as a 257 Weatherby Magnum.What are you basing that on?
