Started this in rimfire but this is probably a better place. old gun I haven't shot in a long time. a group of three different kinds of ammo getting the barrel back dirty and lubed up all the same brand of ammo three different varieties. And then a nice little five shot group. Adjust the point of impact and I'm ready to roll.

Dang that is a nice 5 shot group for sure. I am guessing 50 yards, and a Remington with an aftermarket barrel?
Spec's?

Yes 40x action shilen16 and 1/2 twist barrel 50 yd.

very nice
