Most of the guys bitching about barrel life have never shot out a barrel.
I'm still laughing.... So true.
My 26 shoots 100gr Skinners 4000fps. Seriously.
My 45-70 shoots 400 grainers a bit slower.
What’s yo skinner load in the 26?
A larger bore will always shoot the same wt bullet faster.

Edited to add, 26 Nos, 3,600 fps with 100's generates 60K+ psi, wonder what pressure you're generating at 4K. I'm assuming you clocked that load.
I wouldn't shoot any WT's with that. I once chest shot a WT doe with a 90 gr. Scenar at 3,450 out of my .240 Wby. Made soup of her chest. Once was enough. Nasty clean up at the skinning shed.
