Let's see... If you put it on 60x at 100 yards, that's equivalent to 6x at 10 yards. Most binoculars are 8x or maybe 10x for fullsize. Could you see 22LR holes with 6x binoculars at 10 yards? I could and my vision sucks, so 60x should be plenty for you. You could probably lower the magnification a bit.
