Impressive. I crunched the numbers with the 835.6 and average of 34.5 grains and it came out as 53.5 FPE. Anytime you can get over 50 you've done well. interesting. I have the Factor RC in .25 cal. look forward to seeing what the numbers come up with mine. Thats for taking time to make this video : )
I bought the gun from a PCP selling shop , it was meant to be new, but it obviously wasn't. So I cant say exactly what they did to the gun or the previous owner. However the cocking lever is a bit stiff to cock backwards. So I believe spacers or a more stiff spring was installed, this would make the hammer hit the valve harder. The hammer could also have been upgraded to a heavier one. What I did to increase power was make the transfer port hole larger. So at the end of the barrel there is a small hole drilled. When you shoot the compressed air needs to travel through your transfer port and through this small hole. The standard hole on the barrel is about 4mm in diameter. I drilled it to about 5.2mm in diameter. This allows more air into the barrel and increases your pellet/slug velocity. But you need to be careful if you drill the hole larger, if you drill it too large your pellet/slug can get damaged when you cock, if you damage your pellet/slug it will effect the accuracy of the gun.

Hi Zoltan. If you read further down you will see I replied to someone else who asked the same question.
