Thanks Bill, great offer, but I've got Sub-X rounds and they nearly all go supersonic through my 16.5 inch barrel :oh noes:

Sorry, missed all the replies. Seems like slim pickings. Guess I'll grab whatever is on the shelf and try it.

As per title. My only criteria is that it is actually subsonic when put through a 16.5" barrel. Cheers.

EDIT: Based on personal experience rather than what the manufacturer/retailer states on...
