Has anyone checked their screw/bolt that the cocking level rotates on? Its part number #51. Mine continues to back out. It did not want to add loctite due to the ball and spring that are also in there.
The only thing that I've done was changing out the breech seal (75 Viton) and gave the barrel a good cleaning.
If I were you, I'd move this post to the Daystate Report. Lot's of good interaction with the guys from DaystateUK, Vendors, and Owners. They may have a suggestion for you.
I'm on the fence with getting a RW in .25, how much recoil do you have in the scope? The reason I ask is my Renegade HP in .25 jumps so bad you cant always see the impact in the scope. If the RW HP in .25 has that kind of recoil especially with 34gr JSBs I can see things loosening up. I had several screws get lose on the Renegade. Nothing lose with my .22 RW HP yet.
