I recently bought a HW95 Field Pro. Have 750 shots thru it. The screws always back out, shoots about a quarter size group. After cleaning will occasionally shoot nickel size groups at 20yds. It started squealing when closing on cocking. It has been very inconsistent. It's in .177. Loves JSB or Norma Heavys. Sent the gun back. I'm now thinking of either a TX200 or HW97. This will be for target shooting. Which would be better. I watched a ton of videos and noticed the same squealing on closing after cocking in the HW97 as well. Guess I'm gun shy with the HW line. Your thoughts?
