6 shot and model 37 Winchester single barrel 30" full choke I bought when I was 13.....

I used cci mini mags for years and was always pleased with the performance. Then I started shooting the standard velocity stuff around 1000 FPS and under. I found that the standard velocity ammo on the whole in the bulk of my guns shot much better and the squirrels died just the same.

I shoot winchester wildcats. I drill a small hole in the bullet tip and fill it with spices then seal it with bacon grease.
