Another B50 question/quirk.

I installed an Altaros regulator, filled it to 3000lbs, and shot it. Velocity was 475fps. If I remember correctly, from the dim past, if you fill to 3000lbs it will shoot slow. So, I removed the regulator and the oring was broken. My theory is it broke during installation causing the really slow velocity. Help! Good theory, bad logic, poor memory?

... but mine came way oversprung from the factory. In .177 it was shooting really (really!) hot and shot string was all declining velocity from the get-go. If you fill to 3K without the regulator installed what do you get? If it is still 475FPS then I say you are correct.

I got about 20 shots at about 910fps. Hoping to get it to about 875fps. With the regulator I should get many more shots. When I bought it is had an LW barrel installed. By hit me up I assume you mean my address.

... working from memory here but I recall 30+ shots from my 1500PSI fill in the 12FPE range so with 3K fill and regulator you could probably almost triple that with a proper tune.
