FX Impact Point of Impact Shift due to Silencer

28th June 2020
Today we will be looking at the Point of Impact shift on my FX Mk I when I switch between two silencers, the standard FX silencer/moderator that came with the gun to my new DonnyFl Koi. The change in POI is not because of the silencer but because of the harmonic changes on the barrel. I used 5 different pellets and slugs to demonstrate the massive impact shifts. From the JSB Exact, Heavy , Redesigned and KnockOut slugs plus a local G@ slug. Very interesting, I will need to do some more harmonic work on the gun before I go hunting.
