New information on .300 Blackout subsonics,

thanks to the people at Widener's on their blog.  Including that new(fairly newer, to me at least) Federal 190-grain load, on all six loads, including gel at both 50 and 100 yards, and they tested them from a short 10.5" barrel and a 16" barrel.

Short version: the Federal Fusion did expand some at both distances, nice to know, about as much as the Hornady 190-grain Sub-X.  The best expansion came with Gorilla(which I wasn't familiar with) and Lehigh(had heard of them before.

Good reading on the subject.
