Pellets For .177 PCP

Start off with JSB Exacts @ 8.44 grain and going heavier from there. Also H&N Field Target Trophy @ 8.65 grain with a 452 head works well.

If the gun is shooting above 900 FPS consider getting the heavier pellets because above that speed, they tend to become unstable.

This can only be answered by shooting different pellets to see what the pcp likes. The closest to an answer would be to start with 10 gr. JSB and H&N pellets. One of those two will most likely be the winner.

JSB is the competitors standard for accuracy whether 7.77, 8.44, 10.3 or 13.4 gr depending on the rifle and energy level. Air Arms pellets, I find are excellent for field target too. But as someone else said, you have to try them all to see what your particular gun likes, but they even vary from lot to lot.
