Needs some help with my .22 Marauder

[NMshooter]

My Marauder has been spot on since I got in in February but two weeks ago it started shooting all over the place. Cleaned the barrels and checked the barrel band. No dice, the gun still shooting poorly. This morning, I decided to chrony the shots and found it was all over the place. no wonder it was shooting poorly! The readies were 803, 711, 758, 803, 732,780, 743, 810. The breech O ring appears to be intact. I put an e-mail into Crossman.
Any suggestions from Marauder owners?

Something to check is if the hammer is sticking in the tube. All the holes and slots in the air tube are stamped and can have burs that can cause the hammer to be kind of sticky and erratic in operation. One of the things that one should do when doing any tuning is to disassemble the gun and debur the area where the hammer lives with a Dremel tool and polish the hammer and its chamber. I use dry graphite powder lube. I did all this to mine and it really smoothed out the operation of the gun. It even cocks smoother now. I know its scary for some to take their gun apart but its really not hard if you are handy at all. Its a good way to learn the operation of your gun. The Mrod is known as the tinkers gun so tinker away. There is lots of info on all this stuff on Youtube and at http://www.marauderairrifle.com/forum/index.php?sid=fa38df20d91def90f1d381d49c359235

The striker is known to back out and could be the issue. If it shot fine before, than hammer drag is probably not the issue. You could also have a partially blown TP seal. If you run into dead ends, pm me and we can work it out over the phone.

Thanks guys. I spent some time with my pistol apart and I have been looking for an excuse to take the marauder apart. I will check the transport seal and while I'm at it, I will polish everything up.

I had some problems with mine and replaced the transfer port with some thin poly tube, it works great, might be worth looking into, my TP had previously been misaligned and partially crushed, Neil.

 

[NMshooter]

Thanks Neil.

If you want to try some of the poly tube let me know as I bought about 50 feet of it from e-bay, I will have to dig it out but that's no big deal??? Neil.
