This thing rocks. Don’t have a compressor but bought an Air Venturi hand pump. Couple hundred strokes gets you to 3k+ PSI. After a few shots, 40 strokes or so gets it back to pressure.
Put the scope on it, dropped a bag target at 30 yards and sighted it in. It’s remarkably loud and very accurate. Played around for an hour or so keeping it aired to just over 3k and got the dope for 20-50 yards.
Put a broadhead tHrough the cartilage plate of an old boar at 45 yards. He ran a ways but the lungs were diced up good.
It’s a novelty item but hella fun. Too loud for stealthy shots, and I imagine you’d have string jumpers much over 50 yards. I’ll put the chrono to it someday but it’s fast. Drives the bolts in up to the fletching.
