What are your thoughts on it? If I wanted to run a 22BR My worry is pressure. This was just me sitting in my garage thinking about stupid things because nobody has anything better to do.
5.56 through a 5.56 or 7.62 can is all ready pretty hard to suppress and be consider hearing safe... the BR depending on load is going to be 700-1000 ft/sec faster. Not going to be hearing safe !
