Went out today to do some shooting and had some accuracy and magazine problems with my FX Verminator. Or at least I think its the magazine. First few groups were dead on accurate at 50 yards. Then I had some pellets go out of the groups by a foot or more. At first I thought maybe clipping with my Huggett Moderator but it was on tight and I never had any issues before. I then noticed that the pellet probe was not easily pushing the pellet into the breech and seemed to hang up. At times it would not advance without pulling back the side level again. I put some silicone on the probe and breech o-ring but the cycling problem still persisted. To me it always seemed that the spring tension on the magazine is weak. I'd like your ideas on whats' going on and if there is a video out there on how to clean and adjust your FX magazine. Bill

A quick look at my magazine


 
When you wind it and place the first pellet in from the back skirt first that holds the tension for the rest of the mag. You don't want much tension on the mag as it tends to damage the pellets by placing force on them as they enter the breach. First is the mag tight in the gun? Will it hold itself in position? When you cockl the gun as you push forward on the lever do you feel resistance as you close the lever in the forward position? Should be very smooth you can usually feel the probe going though the breach oring and that is it if it is working properly. Work the lever back and forth with nothing in it that is how it should feel with the magazine and pellets in it. Are you loading the mag properly. It is kind of ass backwards the way you load them. If you have the mag loaded take something like a golf tee and push the pellet out of the mag through the hole like the bolt probe would do. Then pull the tee out, does the next pellet snap into position.? If it isn't and you are loading properly you may have to add tension to the spring. Let me know if that is the case.

Bob thanks for responding to my post. I wasn't clear in that loading the magazine is not a problem. The thing was I don't know how its adjusted and how much tension is required to work well. I followed your advice and did some checking and testing. I have two magazines, the one that is in the gun and mostly used and the one that is used for backup and high volume pesting Today the magazine usually used seemed to function today with out the pellet probe being prevented or hesitating from loading pellets. I then decided to test the other magazine. The tension on the spring was much more and the pellets really snapped into place. In using that magazine the loading lever seemed to load better. Therefore I think the one magazine need more tension. Could you describe how to add tension to that spring. Check out the new video I did on today's testing. Bill

Couple of things Bill with FX mags is more spring tension tends to cause accuracy issues because the tension on the rotor creates more friction on the soft skirt of the pellet. The heavy spring tension was put in for the semi auto FX guns. I run my mags with just enough tension to work maybe a half turn of tension on the rotor. I have found most flyer issues with FX rifles is clipping in the LDC.
Back to the mag, as the pellet is pushed into the breach the spring is pushing the pellet into the side of the rotor and can also clip the edge of the body of the mag causing problems, usually less spring tension is better.spring in mag is simple but you have to go slow. The mag body has a tiny hole that one end of the coil spring goes into and the rotor has the other. Remove screw and slide the plastic cover off while placing a finger over the inner rotor to keep it in place.slowly lift up on the rotor to take it out of body. Once you lift it up about an 1/8 of an inch, the spring will usually unwind, don't stress it is not powerfull. Once they are free look at the two angled ends of the spring those go into the small holes. 
When you put it back together place the spring in the mag body with the spring nub into the hole, place the rotor on top, this is the tricky part but very easy, place the other end of the spring in the small hole in rotor while placing the rotor into body, now look at the rotor it has to kind of pop over the lip in body to have it turn a complete rotation, as you turn it you will feel the spring tighten, slightly pull up on rotor so it can go over the stop.then slide cover over rotor and tighten screw.
Might have to do it a couple times if the spine pops off, but go slow and shouldn't have any problem. This will put plenty of tension on the spring.
I have taken mags apart that have 3 or more rotation of pre tension. Way too much.
Know the likely problem for flyers is probably some clipping issues with the Hugget. Again have not had an FX that I didn't have clipping on guess I'm just really lucky LOL search the site I have posted pictures of the clipping and fixes

Thanks Bob for the detailed explanation. I did read about most FX magazines having too much tension. I will try working on the magazine later. I saw on another site where the guy in addition to adjusting the spring did a little beveling on the magazine parts but I will leave that alone at this point. The guy said to wipe down and clean the magazine with a little alcohol. Should any lubrication be used?. I think I will also see if I can hand load some pellets and see if that works in the accuracy department. Thanks again Bill

"AZBOBCAT"I don't use lube the plastic rotor doesn't need it. Cleaning will be fine.I have opened up the stock FX endcaps and LDC baffles and end caps for ultimate accuracy.
shoot some groups with and without LDC and with and without stock shroud end cap, see what it is doing. pellet guns can be finicky and tinkering can really increase accuracy. Good Luck Buddy

Thanks Buddy, I don't why I assumed your name is Bob but I appreciate your advice again. Bill
