Hi all, I have a Diana outlaw .25. This gun shoots for crap till you get to the last 20 or so shoots before it falls off the regulator. The last 20 or so shoots are very accurate. What is going on with this gun? why can't the first 60 shoot be this accurate also?
I have heard people say they are great guns to tune. Don't have one myself......
Have also heard that they can do with a good service, and that getting it set just right can help.
If the gun is all over the place its going to be finding the sweet spot for the hammer to open the valve. Sounds like the hammer spring is not set right, thus, cannot work correctly to hit the valve and let the air out, and when the pressure drops below the Reg level, the hammer spring starts working because it's what pressure the hammer spring likes. So it could be a case of adjusting the hammer spring. How I don't know, as I don't have one. Hope that kind of makes sense.....not always the best at explaining myself.
Also I have found that a clean barrel always helps, so make sure that is nice and tidy.
However I could be totally wrong and someone else has a magic answer, but its where I would start. Clean barrel, clean internals and then experiment with hammer spring and power output, get them in sync and accuracy will come.
One other thought, if the reg is just too high, it could need reducing ( careful turning down a reg with air in the gun, Degas first )
Check FPS and go from there.
Hope that helps a little. Not much ( am not a gunsmith ) but its a start. Sometimes power is not always King. ?
