I actually like 4x on a .22 pistol on the range. 2x works offhand but if elbows on a bench Id like more mag for shooting 50 to 100 yards.

Just got a stainless original Contender today w 2.5-8x Leupold EER. Has ring marks and is going to the classifieds.

When i set up a deer bbl.it will wear an Aimpoint PRO.
My varmint bbl a 3-12x AO and my rimfire bbl a 4x.

The varmint model will be shot off bags so can go over 4x.

Offhand for me, 4x is max, even w rimfire.
