Much of this is what has me starting down the 300BO slippery slope, 16" in 5.56 just seems like ten pounds of shit in a five pound bag. This first occurred to me when a friend was beside me shooting his 26" R700, and while neither one was hearing safe you didn't feel the blast when the bolt gun was fired. I will always have both, but 300BO seems like it might be better for the things short barrel guns are good for.
I have also had one lower setup with the YHM pull pins, sure is a simple, $18 way to make something fit in a common duffle bag.
