Unless you have a 30+'' barrel I would say you have a chronograph issue.
A while back I built a stw with a 31.4 " barrel and tried to see how much velocity I could get.
With the A Square 140gr loads (Listed at 3500 ft.sec) I got 3590 ft/sec but with hand loads I
managed 3700 ft/sec with decent accuracy. but when I bumped it close to 3800 ft/sec the
bullets failed.(Shed there jackets and accuracy was non existent).
So if you are not having bullet problems then the chronograph is not correct.
