Tuning Got the Gen I .22 Marauder Finished

I had an extra Boyd’s Stock

I bought a barreled Gen I action

I bought a used HUMA Gauge Port regulator. I found a new JSAR Aluminum air tube.

I had a 43 gram MDS hammer made for the tube. The regulator is set at 130 BAR (1885psi)??

I finished it all today and only clipped one o-ring. 

The gauge reads the regulator pressure (1500) and after 35 zeroing shoots the gauge has not moved.

I will shoot a full tank of air tomorrow as I am hoping for 50 shots at 30-35fpe..

Steve,

This particular .22 Gen I enjoys any 5.52mm pellet.

But, today, after I installed the regulator, it is so accurate, I thought I was missing the target.

Albeit, it was only 22 yards but the pellets were stacking in the same hole.

I had to start shooting the numbers on the target to make sure I hitting the target.

I suppose it is the regulated air…
