Recently bought a FX Royale 500 from another member and decided to play a little today. The upper group is with 25 gr. kings and the lower is the 34 gr. heavies. I repeated the same groups many times. Kings are going 913 FPS and the heavies are going 800 FPS. Guess I'll be buying more heavies. The heavies measure 3/4 in. by 3/4 in. and shot at 50 yards. 
What a difference pellets can make...

Indeed. In my Red Wolf .22, I found better groups with the JSB 18 gr vs the 16 gr.
But Kip at AoA suggested I try some H&N Baracuda Match 21 gr and WOW, they shoot the best in my rifle, by far. I'm a big fan of the H&N Baracuda Match 21 gr pellets now! They seem noticeably better quality than the JSBs, though they are a little more expensive. In this case, I am getting what I paid for!

Try shooting the kings at 880fps or lower, you will likely see tighter groups from those as well.

My experience shooting several tins of both pretty much mirrors yours. A couple of suggestions to try. Try the Air Arms 25.40 grain and try the King Heavy 33.95 Gr MKII. I just got done testing several groups of the std King Heavy 33.95 vs the MKII. I really don't know what the difference is in the pellets, but in my gun, the MKII shoots a consistently tighter group.
Good post.

It is interesting how different pellets work in different guns. My Wildcats love the JSB's. I recently bought some Benjamin Discovery pellets that were on sale. They look beautiful. Nice and shiny, no deforms, etc. BUT wouldn't shoot worth a hoot. However, just got a new Hatsan AT44-10S, and of all the many pellets I have, it likes the Discovery pellets! Go figure?

My at 44 loves JSB Heavies and aa feild heavies. It also love the baracuda matches and crosman premier hp and domes. It HATES anything with a pointed tip.

No doubt pellet choice can make or break your accuracy. And it seems really noticeable at longer distances. I remember I picked up some of those crossman destroyers for my Mrod when I first got into pcp airguns. For me they shot like garbage. Never had any issues with the hollows or domed but those destroyers were a$$. Since then I have switched over to jsb, h&n or predator. I still use crossman hollows or domes from time to time though.

Those are MKll I am using. Never bought any of the original style. I think I may try to bump the speed up to around 850 and see how it does.
