I like the idea of those Browes and 300blk Leupys but I think they are tuned for a certain barrel length, grain and corresponding FPS. No guarantee they will match up to your (presumably) Troy 300blk and what bullets you end up using.
I reckon a VX5 or VX6 1-6 with a CDS is ideal though you could only have either the subsonic or supersonic CDS turret on....or just have a cheat sheet on the side of the rifle for both supers and subs and use the standard dial (or any other dial up 1-6ish scope)
