With encouragement from Big E I decided to load up some 44 Magnum fast movers. But I wanted to make it a bit more interesting by testing these loads in a ported vs non-ported barrel. mr.revolverguywww.dayattherange.com

NO EDIT! Velocity testing M855 5.56x45 NATO "Green Tip" in my Colt HBAR Match Sporter and "M4gery" carbine. Shot LIVE at the range - what you see is what you get!
