I'd say a 2-7 mag scope and an 18 FP .22 is absolutely perfect for squizzers
Multishot is handy though, especially when it's cold, or dark, or wet, or all three...
Range depends on your local conditions and the velocity/trajectory... so don;t want to be messing around with holdunder for midrange, as it's way to ocomplicated as you track them through the brances. SO zero so the pellet apogee is never more than 1/4" above centre (i.e not enough to worry about). This will probably land you a zero anywhere between 25 and 30 yards, depening on calibre.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
