My Pulsar is a 22 and I have had no issues until yesterday. After loading a magazine with JSB 15.89s and firing the first round out of the magazine, there was no target strike. I removed the magazine to check and see if a pellet had been loaded and the chamber in the magazine was empty. I thought maybe that the pellet may have hung up in the barrel so I removed the magazine and looked down the barrel and it was clear. This seemed kind of strange I thought maybe the pallet might have exited and just been a flyer that was off target. This morning I returned to shooting and noticed that the pellets were all over the place on the target. I loaded a third magazine to check and see if it was the pellet or some other issue and had the same thing happened with no target strike on the target by a pellet . I removed the magazine and looked down the barrel again but noticed that there seem to be a rattling noise in the shroud. I removed the shroud from the weapon and removed the baffles and spring and the shroud and to my amazement found the baffles riddled with holes and and two pellets.
After investigation, I think i found the root cause of the problem. The allen screws on the Bush (part 32 on parts diagram) were lose enough that the spring tension on the baffles had pushed it down the barrel enough to misalign the it with the shroud. This coupled with not enough spring pressure to firmly hold the baffles in place caused the pellet strike. I noticed that when I unscrewed the shroud that there was little or no spring pressure when the shroud disengaged from the anchor point.
I removed the spring and destroyed baffels, tightened the allen screws on the Bush, reassembled the weapon and it shoots fine now.
Has anyone else had this issue? I have also noticed a 20 fps drop in speed for all pellets on H, M, L setting from three weeks ago. I have an FX chrony and check pellet speed regularly. I changed the batteries yesterday, but the speed degradation remains. Any ideas on what may be causing that? If you own a Pulsar you may want to check and make sure the Bush allen screws have not loosened.
Any help would be appreciated.
