I've had the Logun S16s and never had a problem with pellets jamming, I used Logun Penetrators .22 with a spot of pellet lube on and they never missed a thing.....
Good luck

I've owned the Ultra-Multi Shot and shot the AAs200, if I'd had the choice I would have gone for the AAs200 in .177 ( but's that just my opinion ) hope you enjoy your new gun anyway mate and let's have some pic's up!!

Tried it all, fishing,ferrets,dogs etc but it has got to be shooting for me....don't rightly know? but I can tell you I am at one with the world when I'm out mooching!!
