We have more than a few USHs

My son shoots a 20 using Brenneke 3" mags. He's a crack shot and can make one ragged hole with a few shots at 100 yards.

Never had any issue sighting them in. I just set it in a rest with action open and adjust the scope to what I see thru the barrel. Then it's just a matter of a little tweaking and bingo!

We love our USHs!
