Red Wolf Breech Assembly #51 bolt

Nope, haven't experienced that with my RW.

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.
