Try Benchmark for your AR as it is recommended by many varmint and target shooters - I am using it exclusively now and it works very well.

The last AR loads I put together duplicate Mk242-Mod 0 loads, with 77gr. Sierra OTM bullets over a charge of RL-15 I won't disclose here. It burns quite cleanly and is very accurate.

11e40 - Check out this link --> 223 Rem + 223 AI Cartridge Guide
About 1/3 of the way down the page, the article gives powder suggestions based on bullet weights. Bullet weights in turn are suggested based on the twist rate of your barrels rifling.
In my 1:8 twist, I have found 25.0 grains of H4895 under a 60gr Vmax to be a prairie dogs worst nightmare.
25.0 grains of Varget under a 69gr Sierra Match King is a super accurate paper puncher.
Good luck,

BL-C(2) for 55gr range/social fodder, Varget & 69gr SMK for accuracy work.
Varget doesn't do so well in my XL650. It "sloshes" out when maximum loads are run on it. With the BL-C(2) the case is a little less full and I don't have any problems at all.

I like 24.5 gr. IMR 3031 under a 55 gr. bullet.

I use 23.4 gr of aa2495. COL: 2.250 with a 69 gr Sierra Match King HPBT bullet. With my centurian AR, I am getting 1 1/2 inch groups consistently with a scope, and 3 inch groups with peep sights. I just make sure to use the same kind of head stamped brass because different kinds of 223/556 brass has different water grain capacities. Don't think just because it is 233, it is all the exact same case, and of course the 556 military brass has thicker walls and has less capacity than the 223.

I have used 25.6 gr of 748 with 55gr FMJBT at 2.26" OAL for 25 years in both of my Mini 14's and now my DPMS AR15.

I have mostly been using H335 and IMR 3031 for my 55gr FMJBTWC and 77gr HPBTWC loads.
Lake City Surplus Brass, CCI #41 Aresenal Primers.
Start with a published Low load and work up from there until your load/barrel combination finds a sweet spot.
I AM REALLY EXCITED...I just received an 8lb. jug of the new IMR 8208 XBR powder which has some REAL potential based on the posted data in my .204, 6.8, .223, and .308 loads.
Hello 4 season shooting without pressure of velocity variance...ON ONE POWDER IN 4 CALIBERS!!!

JD 500 Thanks for the .223 link; my buddy at work just got his AR varmint rifle and this should help him get started. I copied the link and passed it along. WG

As you can see, there are a ton of "favorites" in this caliber.
I've used 748 and RL15 with great success. If you want the max accuracy, and pretty good temp insensitivity, go with what the NRA Highpower rifle guys use. If you want cheap, or max # of loads go with something else. My RL15 could do 10s and Xs with iron sights at 600 yds. 1MOA or less with a scope on the informal range. (Okay, it was a National Match AR) This was with widely varying temps.
However, these cases were carefully hand prepped, each load measured individually and great attention given to OAL.
The P-dogs don't really care about all that!

Varget is one of my first choices for .223 for most applications. It works very well in my Armalite SPR with Hornady 55 gr fmjbts, and is even more impressive with target grade bullets. I find it is not a powder that is well suited for progressive press reloading, however. The ball powders work better for that.
2460 is great as well. Same as 748 weight for weight.

My favorite load for my Colt Hbar with a 1 in 7 twist is
77 Gr Sierra match King
24 grains of Varget
Win Small rifle primer
Bullet is seated just so it will fit in the mag
99% of the time it will give me 1/2 inch or under at 100 yars off a bench using a scope. It also give our 600 yard steel 16 inch target a hard time.

+1 H335 for .223 and 7.62x39 loads. H335 and WW-748 are VERY similar powders. I will resist the temptation to say they are the same.
