Jsb .25 heavy mk1 amd mk2 difference?
Probably been discussed before but cannot find comments.
Vulcan .25 mk 1 heavies seem sticky in the magazine, not rotating properly. Would mk2 heavies solve this issue?
Safe shooting

My Kings are shooting at 906 FPS, spiraling noticed at distances greater than 50 yards. It was brought to my attention that there are thin and thick skirts Kings and I believe I got more spirals with the thick skirted Kings. My gun is getting tuned right now and I will see if the barrel polish helped or not, or if Ernest found anything not right with the gun. But no concrete fixed found before shipping off for tune.
