I have a SIII 6-24x50 on a single shot 40-X rimfire, and regularly flog it up down and all around to 350 or better.
Tracking and RTZ has been great.
Takes 51 MOA to reach 350.......
I used to have an 8-32x56 on a 1K BR gun, and when the 10-60's came out, I bought one to replace the 32X.
I thought the 10-60 sucked, fussy parallax, and it got too dark to use at full power.
Took it off & bought a 12x42 NF BR.
The newer SV's are different animal, good reviews on those.
