Looks like it's got plenty of energy for the long haul but DAMN that's got to kick.

LOL...…….. Thus the reason for the T-Rex CSTM brake and IT WORKS. I would never want another radial after having this T-Rex.

I will admit, I'm impressed at just how far muzzleloading has came. There has been a lot of very dedicated people working very hard to make smokeless shooting safe. All the basics still apply and paying attention to your process is a must. I actually changed my entire process after my little ordeal, eliminating non-essential processes.
There was a time I was totally and completely against using smokeless propellants in muzzleloaders. Over the years, reading and paying attention to how the processes were evolving, I slowly started changing my opinion. Well here I am

Do you have an idea of the pressure for that load? How did it shoot?

As for the pressure, you'll have to ask Bestill. Its on the lower end of the charge information he provided me.
As far as how it shot, instant and CLEAN.

Right at 52k in my opinion

I cant find a trace for Benchmark from TGinPA but its a little slower than 3031 and N130 in the burn rate charts. Both those do have traces with 209 primers. I would guess close to 50kpsi with the correct loading pressure. LRMP will yield a little more peak than the old Savage plug 209 traces.
