I read this whole article,

it was a really interesting read...

 ....and my conclusion is that without little bit of machining and changing a longer HS you can't accomplish much more..

correct me if I'm wrong.. but I think that I'm not! 

Precisely. That is what i am trying to explain but, for lack of comprehension, they say you can but you need to do this and that. I said what duh?

Nonetheless, for update, I can now wallop a 33gr slug pass 950 by simply installing the longer HS and replace the HS for the PP kit. 

Happy plinking.

My first FX Impact MK2 PP, 25 cal 700 mm pellet liner, 33.95 grain pellets 926 fps @ 115 bar, I will stop here until I decide maybe ones somewhere in a future to go with slugs. Thanks all for a great help.

As expected bec you have 700mm barrel? Mine is just 600mm

i know what is wrong here 

when u said hammer at max how did u decide that ?

i have two mk2 one with pp and the other without 

the hammer adjuster is different on both 

pp version hammer adjustment has more room to play with 

when u say hammer maxed out that means u barley move the hammer wheel

if u want more fps u should tighten the hammer more cuz i can go up to 950 easily with pp version using 33.5gr NSA

hope my english is clear

Same hammer spring the royale 500, and boss used and many other fx guns.

11500 is the part number if im not mistaken.

Thank you very much Glem.

So in your testings just from the spring I can gain at least 30 fps?

I had a descending shot string on my raptor. But had a lot to do with my tune, I was over dwelling the valve considerably. Once I got my tune to the knee of the bell curve, things got much better. 


according your numbers though, 20fps Extreme spread isn’t bad at all.

That is promising if the poi at 100 meters is within 1MOA. With NSA 26gr, the dev is around 1.1. The King heavy, the deviation is around 2.4.
