My ORION 22cal now fitted with a Gas Ram!

Just to show the power of Nitro Piston see what happen to pellets at 25 Yards

Pellets at 25 Yards.jpg

that looks powerful..... did you chrony you nitro piston rifles... please inform me some values of the chrony results with MS wadcutters
And how accurate is nitro piston rifle compared with a springer precihole or IHP

Regards

Sorry my chronograph is not working
Nitro piston is more accurate & consistent at 25 Yards compare to IHP & Springer Pegasus but if somehow I can manage to lighten the trigger pull just like my IHP than I can shoot ½ “ group at 25-30 Yards
One more thing I like to share my NP Pegasus don’t like light weight pellets
As I again tested my NP Pegasus with Master Shot & RWS 7 grain but both pellets group more than 1.5” at 25 yards but G. Smiths High Impact 9.64 grain groups less than 1 “

Thanks for the reply.
And sorry for asking too much of work from you.
Please post a shot groupings from your NP pegasus
and if possible use audacity method to measure the fps just to get a rough idea of velocity
Even i will do the calculations just send me the sound record or video clip of the shot strings
i will Pm my mail id

hey guys how are you able to fit nitro piston in your orion or pegasus? i mean how do you obtained the piston from precihole. I wanted to convert my orion to nitro piston and so contacted the precihole and they refused to sell me only the piston, saying i will to buy a the whole rifle.

As all of you are very interested to know the velocity of NP air rifle so finally I repaired my chronograph & calculated the velocity of NP Pegasus after firing around 600-700 shot
I used EP Pin as a pellet pusher for all pellets except Air arms
Average velocity of 5 pellets
Air Arms 8.4 grain 798 fps
PH 8.2 grain 802fps
Master Shot flat head 7.48 grain 840 fps
Gsmith high impact 9.6 grain 675 fps

Hi Pratik,
> It's now evident from your test results that "Gas Ram" fitted Pegasus gives consistent 'high velocity' + accuracy...
> Also that velocity increases with the use of lighter pellets...
> However if one were to choose & rely on one pellet for optimum velocity + fpe it would be the "PH 8.2gr @ 802fps, because it's the 'ideal' 12fpe air rifle - Eg: 802 x 802 x 8.2 % 450250 = 12fpe

Wow !!
That's wonderful....
Air Arm seems to be most loved by the PHNP....
Thanks Pratik for sharing.

Has anyone experimented similarly with the .22 caliber Nitro piston precihole air rifle ? Please share if possible.
