shade over 1/2" at 100 yards,
I am sure the gun and I have some room to improve as I get used to it and find some ammo it likes.
Damn, how much does the gun have to like it's ammo??? Sounds like you found a pretty good combination already. The 50 grainers will work fine for plinking and 'dogs. Another you might try is the Hornady loads. They have a bullet similar to the SST that is designed for groundhogs and is devastating (I forgot the name of them, but they have the same red poly tip).
