I had this problem before but thought I'd fixed it , wasn't sure if my muzzle break was giving false readings as the accuracy doesn't seem that effected, usually even with 15fps I'll notice a very slight drop at 45 yds
Mine seems to have settled down now and is respectable at last, hovering around 773 to 782fps over 40.
Last competition chrono checks were779,780, and 781.Glad their not 'hot' or very 'cold', at last!
Tugg give Dave Welham a bell,might be interesting.
