While I can no way fill the void that was created when TGinPA passed, I will share the data that I capture with my Pressure Trace system. Currently I have a Pac-Nor .452", a Brux .458", and a Handi Rifle Buffalo Classic conversion to .458" SML. All of them are using the 209 ignition system. Right now I only have a strain gage on the Brux barreled 700ML. After hunting season I will add gages to the other guns as needed.
I went to the range this weekend and shot some of the big 335 gr APB bullets with H322 and IMR 3031 to prep for dinosaur season. All bullets where full formed, no wads were used, and Fed 209A primers where used for all shots.
