    Especially with 300 mags. Those are made with more clearance at the front rib for loading heavy subsonic bullets longer without pigeon toe.

    There isnít a 300 magazine that I know of with a rib at the case shoulder to prevent a short OAL round from moving forward. I donít know if thatís because nobody making mags understands this or if there isnít enough shoulder on the 300 for a rib to work.

    The best solution at this time is to use ammo with the longer 300 specific bullets loaded to mag length. Like black tip.

    I've been tempted to pick up some of this, but I'm sitting on almost 2 cases of the Barnes 110 grain magic slayer ammo. Still, I'm tempted.

    All of these 110gr loads are supersonic, not subsonic like the guy is asking for. And they take a fair amount of velocity to expand - which drops off quickly in most short barreled 300BLK rifles which makes your lethal range usually pretty short. Look up the minimum reliable expanstion velocity for that bullet, and use a ballistic calculator to plot the velocity of your round at different distances. Not that a hole poked in someone won't still hurt, but it's a far cry from a typical expanding rifle round wound.

    The only subsonic round I'd use for hunting or defense is the Hornady 190fr Sub-X. It's the only one designed to expand at subsonic velocities, and it runs great in my 300BLK. Even that acts more like a heavy pistol round than a real rifle round, but it's way better than a FMJ.
