Well I borrowed a buddy's Browning Buckmark today. A 4 inch slab side barrel with a red-dot type sight.
The temp was 18F with a gray hazy sky. It had a hard time functioning with standard velocity ammo. The groups at 20 yards were not super impressive. You can see the one group I shot at 50 yards using a cheap ( $60 ) yard sale Chinese J21 22 bolt action rifle as a comparison.
Tough choice, as I have quite a few nice ones... but the one everyone always asks to try is the Whitney Wolverine.
