[QUOTE="Ikeman83, post: 2929483, member: 127307"] These cartridges aren't anything like each other: 300 BLK subs are basically a 45 ACP round with a much higher BC that gives 45 ACP velocity for several hundred yards. Supers are basically 7.62x39, (7.62x39 is a terrible choice for this application due to bolt lugs failing. Super fun gun but not something you want your life to depend on) which gets you out to maybe 400 yds. Realistically subs are a 0-100 yd cartridge, and supers are a 0-250 yd cartridge. You can hit targets well beyond those distances, but as far as a reliably consistent engagement distance, that's what you've got. 6.5 Grendel is ballistically excellent, but the mags/lugs have issues. 6 ARC is ballistically excellent, but the mags/lugs have issues. Either of these cartridges will have lots of energy, and are a lot of fun for shooting extended distances, but they have their own issues. Sons of Liberty Gunwerks just got behind a new cartridge that they're supporting called 6mm Maxx. Basically it's a 350 Legend parent case (regular 5.56 bolt face) shooting 6mm bullets with a lot of powder behind them. The only problem for the 6Maxx is that you can't load longer bullets in it. Since your engagement distance is extremely short, the 300 blk probably makes the most sense. [/QUOTE]
