I've shot my benjamin XL 1100 800 times now I'm losing fps and it smokes ? Any h

[Gary J albouthabenjamins]

I first got the Benjamin xl 1100 I did a lot of research about the gun before I bought it that I soon got my purchase and began my work I put a new stoger spring in the trigger workerd out great then I ran a bore snake through the barrel until I saw no grease and blue loctite the side screws and lower trigger screw after that I bought utg high rings with hammers super mag scope 3x9x40 AO MILDOT amazing scope I began to shot and got it to hit quouter sized groups from 40 yards ...
Anyway to my point I've shot the thing over 800 times and it's still smoking I haven't ever added oil !! Never will and now I've dropped about 100 fps ? And about 3 fpe of muzzle energey ? Can someone help please

If it's still smoking, there's probably some grease migrating up to your piston seal. If you are handy, you'll need a spring compressor to disassemble the rifle and wipe excess grease off the piston seal, is this a nitro piston rifle?

I think the seal on the nitro piston has failed my XL shots the same as my prowler 22 cal ..i have another xl and it shot 881 using the same pellet and over 28fpe !!! So is my best bet to contact crossman and get a new one ??it's deffeintly still under warranty and thank you very much to the air gun world

yes it is a benjamin XL 1100 wnp maganum I did take it apart and wiped it clean of grease but I took a look at the seal that's my guess it looks terrible I also noticed the rifel is louder then ever
