My employer just scored a case of the new Black Hills .223 77 grain Tipped Sierra Match King to try out. I shot some groups at 50 and 100 yards with my factory 16" 1-7 twist Colt LE6940 and was very pleased. Grouped just over an inch at 100 yards with 4x optics (which is pretty damn good for that rifle). Here are a couple pics of a round I pulled apart. powder weighed 25 grains. For comparison I included some other 223 BTHP bullets I had laying around, Hornady 75 grain, Berger 73 grain, and Sierra 69 grain. Looks like it would probably give the 75 grain amax a run for its money. I can't wait to see how they expand and/or penetrate (I may have to try one a blacktail deer this year).
P.S. We are still waiting on the .308 version.
