Today, with a nice little Leupold Ultralight scope, the .17 barrel's two best five-shot 100-yard groups through the 455 were under an inch.
The .22 Mag barrel didn't do quite as well, a hair under 1 1/2 inches.
Yesterday, the .22 LR barrel's best was also just a hair under 1 1/2 inches.
Not bad, for a sporter-weight barrel, in variable cloudy lighting.
