With the 69 SMK's, along with FL SB sizing, trimming and cleaning up the burrs. I treat the primer pockets and flash hole and make sure each five round string has brass that weigh close to the same. That's it.

I haven't played with the Hornady products as yet. Not enough to come to any conclusions. I did notice that Hornady makes two completely different 68gr HPBT bullets.
One, with a cannalure, is much shorter (.917") than the one without a cannalure which is just around .983" long. If you find you have the longer bullets, the 1-8" twist should be used.

Generally, each barrel is going to have it's own likes and dislikes, but with these 223/5.56 ARs there are curtain loads (nodes) that most of them seem to like.
Have fun..



Mine are like the ones on the left.

I haven't measured them, but they are for sure the ones without the cannalure.

I've noticed that Hornady has several bullets floating around out there that they don't list anywhere. When I picked up the 69gr's from RMR I also snagged some 62 gr sofpoints (that have a cannalure) and some 62gr OTM (also with cannelure). I think I may have gotten the 62gr's from Midsouth.

Anyway I guess I"m probably gonna have to work up a couple loads anyway, because I won't spend the time on the brass for the SBR that I will for the precision AR, and if I spend that much time on the brass, I will make sure that it stays with the precision AR.
