40.1 gr. H-4350 with a 115 gr. bullet should be running around 2,650 fps out of a 20" bbl, based on Load Data info.
I'm a good bore sighter, too. Can just about put one on the paper at 100 yds.
The Hawkeye borescope lets you look at the bore with a 90* mirror, seeing exactly what the rifling looks like, if there's throat erosion, if there's carbon build up or fouling, if there's pitting, etc.

That's about the velocity I was expecting.
