Trail Boss Giggles

[Witch_Doctor]

Well I have been itching to load subsonics, I got a 5lb jug of Trail Boss, 5000 CCI BR2's, and 180gr Hornady RN in on Friday. I loaded 10 rounds of 9.5gr, 10.0gr, 10.5gr and headed to the range.

I tested each of the loads at 25 yards for potential keyholes, didn't have any of that, so onto the suppressor and chrono. I decided to start at 10.5gr and work down, afterward I probably should have started at 11.0gr considering the 10.5gr chrono'd at 1001 FPS, and I never broke the sound barrier with any of them. The groups were very tight, less than 0.500 MOA and two inches low at 25 yards and 50 yards with an occassional flyer. The flyers came when I dropped below 950 FPS. I will probably load a few in 0.1gr increments to get it as close to 1097 FPS as I can. These are pretty cool as plinking and cool factor loads, thats about it.

Rifle: Remy 700 5R cut to 20" with an AAC Cyclone K
