Picked up a few pounds of Trail Boss a while back and finally had some time available to try my hand at some sub sonic loads for my 6.8. After a bit of reading the directions for Trail Boss, and loading up a few rounds of different powder weights I headed out to my "quick range" just down the road.

The pill of the day was the 115gr Remington FMJ. Workin with the heaviest and lightest loads I confirmed that the bullets were stable in flight by firing at a cardboard box at 50 yards. Unstable rounds would show keyholing. Then the suppressor went on. All rounds were accurate at 50 yards offhand. Using the suppressor I was able to figure out roughly where the 115gr FMJ went supersonic. Back to the bench, where Ioaded up a smaller range of powder weights just below sub sonic. I'll shoot these across the chronagraph for fine tuning and accuracy testing.

Started the same process for 100gr JHP, 130gr PSP, and 150gr PSP but didn't shoot them yet.

Looking forward to being able to launch something larger than .22lr quietly.
