HAM Shooter
I ordered from Archer Airguns and noticed the fellow in some of the photos looked like Stephen Archer. I am going to repeat order, some seal kits, degass tool and another power adjuster. Great prices and fast shipping. Thank you for sending me the whole Discovery valve at the poppet stem price. I had to use that when I screwed up the old valve in my .22 Benjamin Discovery, trying to port it. I picked up a second Discovery in .177 and really liked the power adjuster from the Challenger. I put a little Loctite on it, to keep it from moving. I put a Huma regulator in the .22 and Degassing for tuning became much more important. Now the thing leaks (only 13 year old rifle) and I want to reseal. I did deburr the last time it was apart, and am considering the tool to guide o-rings past the gauge port. The .177 seems to be shooting well with Crosman 10.5 grain, but I want a little more speed. It is shooting at about 16 1/2 ft./lbs at 840 FPS. right now. At least 20 good accurate shots. The .177 was made in 2008 and was still packaged in the box with a pump. Even came with some Discovery 10.5 grain? hollow point pellets in a rubber pouch and a trigger lock called "Crosblock" It is amazing the difference between pumping to 2,000 psi vs. 3,000 psi, in essentially the same air rifle. The .22 gets 24, 26 ft/lb shots vs. the .177's 20+ 16.5 ft/lb shots. I use these for hunting small game.
