Tuning FX Impact M4 Extended wih 37gr ZAN Slugs, Part 1

[@PaulHamM3]

So with the standard 700mm superior liner, my .25 M3 grouped really well with 41g slugs at 960fps, it would be really interesting to see what this newer 800mm heavy barrel can do with different slugs/ weights, the lower reg pressure needed to get these slugs to the same velocity as the 700mm is a real bonus, i think you are the first person on youtube to show what the .25 800mm can do.

Very interesting video Chris,I have the FX impact .25 FAC with the 700mm barrel /standard STX and you were completely correct, I to got carried away with buying different pellets and slugs and found myself getting confused and distracted.I have decided to go back to pellets and find a consistent/accurate set up .

Good video, tuning these guns can be long time consuming process, done a lot of tuning over the last few years and one major thing I’ve noticed is chasing low ES is not the most important thing in the world, I’ve shot all my best 100m groups (14mm) with es of around 25fps. At 50m with a 25fps they will still be going through the same hole! More of these vids! 👌👍

Hi quick question do all fx impact fac come slug ready as in the barrel/liner taking in consideration the model like compact, normal, sniper or extended? I'm intending to buy a fx impact 22 sniper fac but I need to know if barrel/ liner for slugs and pellets is an extra option.

What did the rifle start of in the reg at the back Chris on the extended just wondering what the difference is Between it and the 700 when you get it

Maybe You could explain this, for a rifle with no hammer adjustment and valve adjustment, only a regulator, how can the regulator be adjusted to have a constant shoot when the valve is pushing at a certain lb as air goes through it and the hammer, also unable to regulate, is pushing the valve at a constant lb?
