TRS1,
In the days when I hunted, I used my 0.177" TX200, Crosman Accupel, with a Simmons Whitetail Classic 1-5x20, set at 3X.
I then moved to hunting with my customized rimfire BSA 12/15 0.22LR, also using the Simmons Whitetail Classic 1-5x20, set at 3X.
The 12/15 was a stunningly good rabbit rifle.
Have fun & a good weekend
Best regards
Russ
