Fantastic work!

How did you manage to attach the 22ci tank to the 1250 regulated valve?? Or is it a plain RWS 850 valve??

Nice job with the stock also

I am a boilermaker / fitter & turner by trade, so several hours of machining and checking the fit up saw me produce my own adapter. I retained the original 1250 valve body but bored out the firing chamber by about 2.5mm, i also opened up the mouth of the valve as per Roald's tutorial.

when i opened the valve originally, the return spring behind the valve stem was cocked over quited badly (deseated from its recess,) so i included a aluminium spring guide on the end of the paintball tank adapted to keep the spring central, thus increaseing the efficiency of the valve opening and closing.

It is now giving me 40 consitent shots at 925FPS giving me exactly 30FPE using RWS Super Field pellets (which i weight sort to 1/10th of a grain batches, i am curently using 15.8 grain batch)

Accuraccy is quite good. 8 shots into 8 mm at 25 yards off bi-pod and rear bag. i havent tested it at 50 yards yet as i just haven't had the time. but, i've shot plenty of birds and rabbits at that range and they have't run off saying "better luck next time" they haven't said anything because they're stone cold DEAD!

I will post some pics of the action internals, however I never actually took photos of the valve internals and i really don't want to take it all apart, just for the sake of photos, sorry. I do however have a spare 1250 valve and hammer set that I want to modify at some point in the near future. I want to bore the valve right out, about 5-6mm, add a heavier return spring inside the valve so that it closes much quicker. This means the air burst will be much sharper, have a higher spike in the fire sequence, which means much more efficent use of air, i.e. more shots per fill, lower exteme spread and slightly higher power. I might even add some lead to the spare hammer to give it a heavier strike. I'd love to get it to around 35-36 FPE. We will just have to see.

untill then, here are some more pics of the rifle.

oh, and a link to a crow i shot a while back. its all in slow motion so watch for the pellet in flight

happy shootin

Its American walnut and the adjustable butt pad is silky oak. You can't see it in the photos but, it gives thumb up and a wrap around thumb shelf for the standard pistol grip hold.
