When the spring in mine, equipped with a Vortex kit got tired and lost a lot of its punch, the gun was shooting JSB 8.44 domes in the high 600 F.P.S. That is not much power at all, BUT with no wind, the accuracy was beyond belief. The shot cycle was deceptively smooth with virtually no bounce at all.
600 F.P.S. is just too slow so I put a Vortek PG 4 steel kit in it that took a while to settle down. I am now pretty much back to the accuracy I had at 600. The gun is pushing about 825 now and that is where I want it to be. The only noticeable difference is more recoil, but that is to be expected.
