Sierra 60 Grain HP in AR 15

[Bigame1]

Hello:
Has anyone loaded this bullet for the AR platform and if so what powders have shown excellent results?
I'm going to load some up for a Stag upper with a 1:8 twist have all the powder and primers so just need to know what works and I can go from there with my testing. I'll be using LC brass and what ever primer I need as I have all of the small primers,powder etc.

Thank you for all of your information.

In my Colt HBar, 25g of Varget with the Sierra 60g HP shoots incredible groups at 300 yards. My barrel is a 9 twist. Lake City brass and Fed 205M primers. I drop my loads with a Harrell's powder measure and standard deviation is less than 10fps.

In Rock River 1-8 twist, LC brass, Winchester primmer, 24.4 grains. of IMR4895 .
Shoots half minute at 100 yds. Does very well on P dogs.

+1 for the Varget load. It shoots really well out of my buddy's 18" 1/8 twist Wilson Combat barreled rifle.

I have had great luck with the Sierra 60 HP in my ARs. In my Rock River A$ Varmint with 24" 1:8 barrel I use LC brass, 26.5 Varget (need drop tube), Federal Small Rifle primer and get 3254 fps. My Rock River HBAR SS 20" 1:8 I use 26 Varget, LC brass, and a Winchester small rifle primer for 3060 fps. Both rifles will shoot between 1/2 to 3/4 MOA with these loads. My son-in-law nailed a prairie dog at 405 yards with the Varmint 24" AR. I have some Hornady 60 grain soft points ready to test now as they are about $3 a box cheaper than the Sierra HP.

Not the Siera but the 60 gr Vmax on top of 22.3 gr of accurate arms 2200 is absolutely awesome in my 1-7 twist SPR. Easy under MOA out 300. Not so good at 600 however as wind moves them around pretty good.
