I recently got one of these guns, and I was really impressed with the nice walnut stock … nice grain, good finish, and decent design. Unfortunately the singleshot adapter sent from the seller was the wrong caliber, and the magazines were too tight a fit due to the central screw in each protruding a slight amount too much.
I sanded the protruding screw til the mag fit, and started shooting. First off, the gun shot hard and accurately, but over the chrono, shot velocity dropped a bit with every shot, an indication the striker spring is too strong at the recommended fill pressure.
One screw got the action out of then stock, and a pin needs pushed out the side to remove the springn cap (hold the cap in as you remove the pin to keep it from flying somewhere). I then trimmed the spring a half coil at a time (and retested velocity consistency until it was what i wanted ….. a slight increase in velocity of around 10fps over then first ten shots, the a VERY consistent string for around 60 shots, then a gradual falling off until I stopped when it was down 15fps from peak at almost 80 shots! Yes, an unregulated .22 cal giving over 70 consistent shots from 3000psi down to about 1900psi!
The trigger was ok, but a little heavy, so I did a “slot lube” and adjusted the seafr engagement screw, for a nicer break of around 10oz.
Yes, power was lower than advertised … initially I got about 32fpe the first couple shots, with a gradual decline over around 20 shots until the poi had dropped more than I wanted to deal with. After trimming the spring, the power was around 23.5 fpe, at max setting (I didnt play with the power adjuster since I hardly see a use for it the way I use airguns) but the curve was so flat I could easily use the same hold at 50 yards for over 70 shots on the same charge. And that hold allowed consistent hits off a front bag with the stock shouldered on 1” shoot&see dots at 50 yards outdoors in the breeze! I scored around 65% solid first shot hits, and about 15% “clips” with no little waiting for the wind and fairly fast shooting with a 16X scope. I mostly used tweezers to single load the rifle, as I don’t really care for magazine loading when testing accuracy.
The gun was louder than a Marauder by a lot as received, but is now only a little louder than the mrod.
Despite not having a decent single-load adapter, I LOVE this rifle!
I’m tempted to polish the barrel’s rifling, add a front barrel shroud support, and really tune the trigger … and then if it can make a decent benchrest gun.
