I started working on a used .25 I just received yesterday. Bought it as a project gun and decided to start with a low power tune. I have never tried to tune one for low power and high shot count. I always opt for horsepower.
After full teardown and honing the airtube, I removed the lawyer spring and set the trigger for a single stage pull of 7oz. I always throw away the stock depinger as I feel they are worthless and just take up volume.
I did open the gauge block and increased volume and flow of the valve. Changed hammer spring, but left everything else stock.
From a 3000psi fill, my first string was 48 shots at 800fps with JSB kings. Not to bad of a start. Hope to play with tuning later today and see how much improvement I can make.
