Loads for 77gr SMKs and a 24" AR

[Sgt_Jamez]

Most of the .223 loads I read about are for bolt rifles. I saw the load data from Sierra specifically for ARs, but I am wondering if you guys would like to share your 77gr loads?

I have a brand new DPMS 24" stainless bull barrel 1:8" twist. I have 69gr and 77gr SMKs and 69gr Nosler Cust Comp slugs.

Recipes anyone?

Thanks!

Here is a direct link, but try the Reloading Depot section at the top of the Reloading page and look at .223

24gr Varget or Re15 with 77SMK at 2.255 is a pretty standard load for XTC in an AR15. Obviously you'll want to fine tune to your rifle. The chamber you have makes a big difference. My CLE upper with its tight chamber needs lower loads. I use 23.8 gr Re15 for it with LC brass and CCI#41 primers.

+1 on what JCummings posted. I'm using 24.0 Re15, LC Brass, Rem 7 1/2 primers out of my 20" Krieger barrel with the CLE chamber...

Excellent performance from Ramshot TAC for both the 69's and 75's in an AR platform.

Start at around 24 grains and work it for your gun.

With the 69 smk try 26. varget. It has shot well in several AR platforms of mine. It my go to load.
