So far the jsb exact 4.53 don't seem to group well neither do the heavies. I have had best results with the exact 4.51 and airarms 4.52
Here are some 8 shot groups at 30 meters. Now I'm not the best shot in the world and the cat is still very new to me.

I know holes on paper in pictures are not easy to judge so I used a 5p to cover the groups.


The other groups I was not able to cover with a 5 pence.
I then went on to see if I could repeat my results with the two better grouping pellets.



As you can see I was able to cover the 8 shot groups with a 5p again. So far the cat seems to favour the exact 4.51 and airarms field 4.52 there really is little to separate them. I have not tried anything over the chrono as I was simply looking for groupings. I have some sample packs of h&n ftt and sniper medium and light on the way to try. Will see if they fair any better.
