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?

I have been thinking about getting a tin of them, but the only one I now has them is Straight Shooter Precision Airguns and they hit you for $13 shipping for one tin of pellets.

Looks like my 25 Cricket at 956 fps with 25.4 gr. Jsb,s definately outperforms the wildcat

I knew a guy that had a .25 Cricket and his out of the box shot H&N Barracudas at 780fps. He was all bummed out, and ended up selling the gun.

Out of the box before tune mine was 970 fps with jsb 25.4

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.
