An over-do update.
When we got home Norma Jean was put in the cabinet and it was time to get the rifles ready for EBR…..EBR is now long gone and I pulled NJ out and put her on a chrono….650 FPS

No wonder I was hitting low at longer distances. The first day we were shooting at 750 FPS.
Opened NJ up and the spring inside was shorter than the new one I had so I replaced it. 650 FPS.

Next I put a new piston seal in. 650 FPS


Last but not least I changed out the breech Orings, but I had done that before PAC….650 FPS.


I was now very pissed off so I took a step back and put NJ back in the cabinet for a time-out !!!
I called the great Cameron K. and talked for a few minutes. He told me there was an Oring on “The large black nut on the compression tube”. Cameron warned me I might have to use a lot of heat to break all the locktite the Brits like to use.
With the tube in the padded jaws of my vice, I got busy. With a little AC/DC music pumping through my ears I was ready. I grabbed the proper sized wrench and addressed my compression tube.. Well, no heat was needed, no AC/DC was needed to get the blood pressure up, the damn nut came right off.
And here is the Oring I found.

Gee, wonder if this was the issue
Got her all back together and started shooting her. 880 FPS with 8.4’s…..After about 75 pellets she has settled in at 850 FPS.
After Thanksgiving, and weather permitting, I will get her setup again for HFT. She is shooting about 100 FPS faster, but let’s see how NJ does.
