I have an Impact and strive to get the best from what I think is the best diablo pellet on the market the “.25 King Heavies”
This pellet has a bc in most barrels above .05 and has been the winning pellet in windy conditions at EBR for the last 2 years.
What has this got to do with the new 700mm barrel about to hit the market?
You would think maybe the current fx barrels are getting the best from this pellet already but I don’t think they are.
In my opinion the best barrel for this pellet at the moment is the Lothar Walther polygon barrel and I’m not the only one. RAW fits these barrels to the hm1000x a gun designed around the King Heavy pellet.
This gun can send a King Heavy pellet at around 900fps and produce sub moa groups with high frequency.
So I fitted one of LW polygon barrels to my Impact. It worked well but I felt it lacked the speed I needed to produce the spin rate on the pellet to really get it stable at longer distances (100y)
With some modifications I have managed to get the speed up to 890fps and now I really happy with the accuracy. I can achieve sub moa groups at 100y and 60fpe of power.
The down side to this is
1: More Noise
2: More recoil
3: Low shot count
4: A not so relaxing gun to shoot.
So now what should the 700mm barrel offer?
1: A 10% increase in velocity.
So if in its standard form the Impact can shoot a King Heavy at 850fps you will now get 935fps!
So realistically will have to turn down the power with reg and hammer spring for best accuracy.
2: With less required air there will be an increase in shot count.
3: Longer barrels are quieter barrels but add to this to the fact you are using less air and it will be quieter again
4: Less air can also mean less air turbulence and a more accurate gun.
5: Custom twist rates to match the pellet perfectly.
6: Less recoil and a happier and easier gun to shoot.
Down side
1: An extra 100mm of barrel.
Not a big deal on an Impact really.
Im excited about these new barrels.
Im interested in what plans others have for the 700mm barrels
Caliber?Slugs?pellets ?twist rates?
