| The last P Series I owned, I disabled the velocity adjuster by removing the BB, and filled it with JB Weld.
I continued to fill the front of the bolt, which I later redrilled, but with a much tighter exit in hopes of retaining more in my 12g case. It worked, but not to the extent I was hoping for.
Most shots I was ever able to get were 20, sometimes 22 at best Velo. |
