Ruger 10/22, small .22lr carbine that with good brand new ammo gives good accuracy out to 300 feet normally.
Some of the shots seemed soft, the puny kick of the 10/22 seemed even punier on those.
They were off by as much as three inches at most.
But the rounds that still had oomph to them were dead on out to 300 feet.
(Range is a small range.)
Pretty much I figure I will have ot burn up the remaining 250 rounds and buy new ammo.
Especially since the rounds have been sitting since 1998.
(Had a heck of a time finding a range.)
I'd recommend picking up a few boxes of Super-X ($2 per 50). 40 gr. Should produce around 1200 fps out of a 16" barrel.
Are you still in New York? Be glad you can still find a range at all up there. I can ask around and see if there is anything else in your neck of the woods if you want...
