Your Best AR 556 Handload

[HighKnob]

I'm really interested in heavy 69+ bullets that will fit AR mag. I need a new powder to start. I've used RL7, BLC2, Varget, mostly Varget, but I think I need something faster for the small area inside the case after seating those long bullets. Would love to hear what you think.

 

[Outlaw6.0]

68grn Hornady Match pushed by Varget. Sub Moa @ 100yds with my 16" Stag & 4x scope. Shoots well in a multiple AR's & even a couple bolt guns.

62gr Speer FMJBT with H335. Same velocity (2950fps) and bullet weight as military M855 BALL. Shoots sub MOA out of a Bushmaster XM15 Patrolman carbine with 16" barrel 1-9 twist. For heavy bullets, shoot 69gr SMK with H335.

69 Grainer of your choice on top of 24 grains +/- a 10ths or two of 8208 XBR seated to 2.255 should get you exactly what you're looking for, that is if you're looking for 1/2 MOA or better 5-10 shot groups.

Or, for heavier bullets in the 75-77 range use 23.3 grains +/- a couple 10ths of 8208 XBR for outstanding results.

Same results for me with a DPMS 24" using Varget 24 1/2 grs for the 69 and 24grs using the 75-77

I use 24.5gr varget, LC case, 77smk, fed205m. Seat to just fit in mag. Shoot great out to 500.

There was a standard match load I found: Win cases, Rem 7.5 primers, 69 gr. Match Kings, over 25-25.5 gr of RL-15.

In my 20" this was 1/2", with ca. 2900 FPS

69grain SMK or 68grain Hornady HPBT launched with 25.5grain of RL15 lit by Fed primer.

I don't know what 20" you have but around 2700 fps is usually the accuracy velocity. 2900 is over max. good luck with that speedster. ART

I have a 20" RRA with the Wylde chamber. I found this load in the Alliant catalog, which lists the max as 25.5 gr with the 69 gr. Matchking at 2956 fps with RL-15.

Sierra also lists a max load for a standard 1:7/16" AR, of 25.7 gr with the same bullet and RL-15.

I tried loads from 24 up to 25 gr, and settled on the 25.

Check out the link below for a number of service rifle loads, mostly with heavier bullets...
