G'day All,
Anyone got a fix for creeping MV over the bottle fill?? I run 25.39gr JSB.
I fill my bottle to 230bar, then I get consistant MV at 885fps avg for around 30 shots and then the MV Avg starts creeping up. Ends up low 900fps range after 60 shots which is where it falls off the reg at approx 150Bar. My hammer spring is set to give 885fps which I find gives good accuracy but that goes when it starts creeping and also POI shifts up. The Tune is lower then the tune the rifle came with but I had no joy with that accuracy wise with 25.39gr JSB Monsters.
