AEA Challenger .357 pcp air rifle. It's pushing 82 grain pellets super sonic. I need to pick out a mold to cast some heavier slugs. The 82gr pellets at 1200 fps deliver 261# at the muzzle. That's about midrange .38 special power, straight out of the box. With the right slug and a little tuning it will do over 400 foot pounds.
I need to get a suppressor for it, the neighbors called the sheriff's office on me and I live on 50 acres in the county. It was pretty funny to me, because when I saw the deputy drive by from the front porch I thought about having to explain that I was shooting a pellet gun. In fairness to the neighbor though, we have new neighbors on the other side that I have almost called the law on. Shortly after they moved in, they started shooting after dark. One night they were doing mag dumps with something like a 10 round 9mm at 11pm, and occasionally you would hear a hand cannon. About 10 minutes after I saw the deputy drive by, I walked out the front door and saw the deputy walking through our side yard. He came through the woods from the neighbor's house. I wasn't too happy about that, but at least he saw my backstop so he really wasn't concerned when I spoke with him.
