Put the scope back on and pumped up the 850 over last night and this morning to 2200#, that's about 570 strokes with the Benji pump. Went out to our new property this morning and as I pull up there are some starlings in the locust trees. I put in a magazine of Crosman standard pointed pellets and had no idea where they would hit. I cranked the scope to 9X and let one fly. I wasn't sure if I hit it by sight because there was a lot of other birds flying but I could hear the tell-tale whop sound. A couple seconds later it fell out of the tree. I walked over to it and put it out of it's convulsions. There was another squacking sound and I slowly looked around and there was another starling about 35 yards away in a different tree. I put the crosshairs on it and it dropped as well. After remounting a scope, changing velocity and know having zeroed the AR, I would have bet money on misses on both. Didn't get a picture. Sorry.
Now on to the important stuff. After the first round of mods, tt's now shooting right around 800fps with standard 14.X grain pellets. RWS H-points average 797fps, RWS Superpoints average 795fps, RWS Superdomes average 810fps, JSB Jumbo Express average 808 fps, Crosman standard pointed average 795fps.
I shot four groups with these pellets off a bench at 20 yards, see picture below. The RWS groups were 8 shots, the JSB were 5 shots. I didn't get a picture of the Crosman pellets but they did much better than yesterday, one jagged hole about 1/2" across.
