I have had a funny / unexpected result with subs in my EM, they all crack trans-sonic through the suppressor so they are going faster than the same ammo in a Stirling and two JW15's. Not that I have shot them over the chrony to see how much actual difference there is. Any ideas apart from hacksaw?
Re Dampeners, 303's always shot best with a bit of tire tube between the fore-end tip and barrel as a tuner. After watching the earlier link I posted I got to thinking that most 22's would benefit from the rubber dampener
