Reply To: Getting My 22 Cal Hatsan AT44s 10 Long Ready ;- )
When I had mine in stock condition it shot the 18 gr pellets in the high 900 fps, around 970 fps at the highest. I had a lot of mods done, valve mod, barrel crown, trigger (13 oz), transfer port opened) to it and had to drop a regulator in to get the speed down. After all the mods I had it shooting the JSB 18 gr pellets @ 895 fps for 40 shots with a 3200 psi fill. I traded it for a high end gun not too long ago. I really like the action of the AT44s. I still have a 25 cal long and 25 cal short.
