That looks to be a superb load with the 550-gr WFNGC. What alloy is your bullet metal ?
Nice work with the pneumatic recoil reducer too. I have two PAST pads of yore, a thin one and a thicker "Magnum" pad in shoulder harnesses. My little block of high-density foam rubber about 1.75" thick (cut from a seat cushion) works much better at the bench, and it stays at the bench so I do not walk around wearing a sissy pad for all to see at the public range.
