Wildcat Issues

Hey guys. I was wondering if anyone has shot the jsb heavies 33.95 mk1 and mk2's through their wildcat and the difference if any? I have the mk1's, and noticed when I load the mag and push the cocking lever forward that there is some resistance due to the skirt diameter. I also feel the skirts scraping as their pushed into the breech. Having said that the accuracy at 50 yds is excellent. 1/2 in group's are achievable if I do my part, but when I shoot 100+ yds the groups open up to 5 inches. This should not happen. I'm wondering if any damage to the skirts being slightly forced into the breech would cause this issue at those distances? but to be so accurate at 50 leaves me confused. I'm wondering how well the mk 2's shoot in this rifle? I'm going to manually push some pellets through the breech block and the barrel and inspect them. I also want to get some mk2's . Has anyone experienced this?

Do you sort your pellets?
Just got mine back from AOA for tune due to poor accuracy and also added no limits mounts when I discovered my Hawk Eclipse was near its vertical adjustment limits.
Went to range today and 50 yd groups are between 0.4 to just slightly larger than 0.5 inches.
At 55 yds groups jump to almost 1 inch and at 60 yds are in the 1 1/2 inh range.
Wind varied but not over 2.5 mph with changing directions.
Cant figure it out unless its the pellets. Currently not sorting.
Any help would be appreciated.
 
Hi all. Op here. Just went to go shoot my wildcat yesterday for the first time in 4 months (very busy at work) and it was out of air.... Surely I didn't run it all the way empty. Started to fill it up and wont get passed 25bar. Bleeds to zero in seconds. Who knows when it happened. Had it repaired by AOA one year ago to date. Didn't even last that long. Hopefully its just an O-ring.
