Well, the weather sucked all day Saturday, and today was a pile of domestic drama/chores. I just set the chrono out the door before it got too dark and shot the 5 benchmark loaded rounds that I had left over. I shot 5 factory Hornadys first to be sure the chrono was going to read everything ok.
I'll post detailed numbers if anyone wants them, but the numbers suck, so there isn't a lot of use for them in my book.
Temperature: 70 deg. F.
Chrono distance: 15 feet from the suppressor front end cap
10.5" AA upper (chrome Sabre bore)
Factory Hornady 123gr. Amax load
Average Velocity: 2214fps
85gr. Sierra HP handload (31gr. Benchmark, CCI #450, AA/Lapua brass)
Average Velocity: 2395fps
The 85gr. sierra load showed no pressure signs FWIW.
Guess I'll skip Benchmark...
Later when I get a chance I'll try the H335 and see what happens.
