Sort of off topic, but I bought a Hatsan 95 springer last summer in .177. I bought it from Pyramyd and paid $10 extra for their "10 for $10" checkoff. Looking at their chrony printout, their first shot was over 1200 fps! After that it came down to 900+ range for the remaining 9 shots. The very first shot I took sounded like a .22 rifle! I have cleaned the bore several times with patches and Kroil to remove what looked like traces of light rust. After about 300 shots it is hitting 950 fps with Air Arms Diablo Express 7.87 grain pellets. My rifle also has a crunchy cocking feel to it. I have not taken it apart but did apply a little Air Venturi "Tune in a Tube" to the mainspring as best as I could access. The cocking and firing cycle seems to be a little better, but it needs more break-in probably.
Im really not liking the side to side play my trigger blade has.. part near a 3/8in side to side
