Now, I stumbled across this and just a few minutes ago identified my Buffalo Hunter. Yes, they were pushing 610 MINI with 125 FFF out of this thing.
I was shooting RB with 120 gr FF yesterday, and it was a bit stiff. Dropped to 100 gr and much more pleasant.
Call it a 26" barrel with 1:66
I am still taming it, my first experiments with 60 gr FF were poor, but up to 100 FF and it started to perform a bit. I have a lot to learn as Dad was killing paper plates with it at 400 yards, I am nowhere close to that. I have yet to try the Mini
