Before you all go running hooting and uh hollering yelling that’s over book max by 2 grains. Take your cheap asses and buy a hornady Manual look up 5.56 load data for a 80gr bullet with AR comp..


I use a lot of AR Comp too & my loads are higher that most (early) data for it, so I'm not too concerned until I try a given load.........................you are also seating that bullet out a ways as well & I don't believe it will seat at mag length, even ASC's w/o being into the ogive a little bit. I'm not going to single load anything.

Here are some links to a whole series or various powder tests all done with 77 gr SMK's intended to attempt to dupe MK 262 loads; pretty interesting data & on the powders that I use that he tested, it's pretty close to my results. At least it's a good reality check. Part of about a 10 part series, IIRC.
