Anybody out there been using one of the super short mags? I see Midway has Winchester or Hornady brass available for the 243. Seems like it'd be a fun little rifle to play with, and they can just about be had for a song. From what I can tell, it's got it's own little niche for people wanting more horsepower out of the standard AR-15 sized platform. If one were going to get a bolt gun, is Browning the way to go? I've read reports that the Winchester's experienced feeding issues more so than their buckmark counterparts.
