Air Arms S 510 xtra .22 Cal.Rotary mag

[kiwi Rabbiter]

Hi, To all Air Arms S 510 xtra .22 Cal owners, Do you ever have problems with the rotary 10 shot mag. at all.? I have been having a spot of bother every now and again with the odd pellet jamming up, so the recycling of the mag gets stuck. Finally after a while, it will release the mag after much shoving and pushing and cursing, I find that the pellet is either flatten or squashed a bit at the skirt where it has jammed up.? I am using at the moment Diabolo 5.52 size 16 grains. I was wondering if the odd pellet was falling through a bit and jamming on the cycling of the mag.
Any help would be appreciated. Thanks.
