Some Ballistic Adventure

Got an hour or two range time; a clip of breaking in the new Springfield Ronin 1911 in 10MM. No sense in shooting 10mm unless you’re shooting full house loads, right? This is the Underwood 155 grain XTP load, clocked at 1500 fps, with 700 ft/lbs muzzle energy. And a wicked muzzle flash. Most likely not going to be a carry round. With as much unburned powder most likely would work better in a carbine!
