    Anyone using AR comp? Found a 8lb jug for $141 so I picked it up. I know its been out a while. My quick research says its rl15 modified to be less temp sensitive.

    I’ll look up some relaod data didnt know if any service rifle guys have a go to load for 77 smks (of course start low work up...)

    I am using it in a 6X45 AR that I built and it is working really well for bullets in the 80-90 grain range.

    I've been using it for years as my primary powder for NRA/CMP .223 service rifle loads, having switched over from Varget. Other than being on the dirty side, it's a great powder and I've been pleased with it's performance. I'm mainly using it with 77gr/82gr bullets.

    I use it for Service Rifle and load 22.8gr for 52, 69, 77 & 80gr bullets. I've shot my PBs with it and it is very temp stable. The last group I shot with it was a 3 shot at 100 yards using iron sights that was under .3". The 80gr loads will shoot within a 3" spotter at 600 using dumped charges from a Lee Perfect.
    It's been very clean too. I only clean about every 250-500 rounds.

    I love this powder. Has a burn rate very close to H4895. I’ve used it in everything with great results. Works better with heavier bullets in 223,68 grain and up. Have used it with 50 and 55 grain but velocity was mediocre at best. A great powder for 308 also. My 243 likes it to with light bullets (55 and 60 grain).

    I use the same service rifle 22.8 load for 80's as Beau. For 69 Sierra TMK, and 77 HPBT's I drop down to 22.7 because I load those on a progressive Hornady and I want a little cushion on charges that might be over. For the 52 grain bullets I found that 24.7 hammers.

    What is your load for the 6x45? Waiting on a barrel for a bolt action build. I use AR-Comp with the 70gr RDF in my 223 bolt and it shoots incredibly well.

    My best load is as follows:

    Case Case Length Primer Powder Charge Wt. Bullet COAL
    FC 1.750" CCI 400 AR COMP 25.5 Sierra 80 gr. SSP 2.260"

    This load is a consistent 1/2MOA load for me. I am averaging about 2690 fps out of my 20" BHW barrel.

    Who me, or HandgunHTR?
    I'm still in process of finding optimum load.
    Best load to date is 26.9gr imr4895 with a
    70gr nosler Armageddon, cci450's to light the fire. 24" BHW barrel..29" in first round of testing, 2.373 coal.
    25.6 benchmark shot a .45, but wasn't able to repeat, opened up to .66, probably me.
    Now I'm going to start over eith bergers
    70 gr varmint. I just picked up W748, BL-C2 to try also.

    My 65 Grendel loves it in 123 gr bullets. 27.6 gr for many is a sweet spot
