After some help on loads I got my subsonic load working pretty good. It currently varies from 990-1005fps .

I'm using Trail Boss powder and Hornady 170gr FP bullets in an 18" savage with a YHM suppressor.

Here's the 3 videos, supersonic, supersonic suppressed, and subsonic suppressed.

Its quite an amazing difference. The down side is the dope. The first 3-5 shots get sub MOA groups, but it quickly fouls producing 1-1.5" groups. I have to give it 10.5" at 100 yards. I haven't even bothered figuring the dope for 200.

I think the most I would try to take at 100 with this round is a yote or a jack rabbit.

Enjoy
