I would like to try some new hunting loads for an 18" AR10 in 308. These will be 150 gr. Accubond loads and I like to get good velocities. Already have the bullets. I will be using brass from the usual suspects and cci 200 primers probably. Maybe BR2. H4895 has been my standby. I am reading about some other good ones as well. What have you tried in this situation. I would like to hear any input. Theres a ton of input for guys wanting to shoot 168-175 gr. Not so much for the 150 gr. loads I think. I am seeing good data for N135, AR Comp, Tac, Accurate powders as well. Varget is good too, but also like h4895 can be hard to find. These are not target loads. Thanks.
 
I have done well with IMR4895. AA2520 was my old standby. For a long time it was unobtainium. I stay away from Reloader Powders. The bottle is too tall for my shelf. Your going to get a lot of responses. These were for the DPMS AR10 I used to own before the unsafe act was passed in NY. A lot of good powders out there for .308. I tried Varget, IMR4064, and some others that don't come to mind right now. IMR4895 worked well for me.
 
I can't help much. I use H4895 for both match loads with 175 grain bullets and hunting loads with 165 grain bullets out of my LR308 with a Criterion 18.5" barrel. It just works...and well.
 
I run 44.0 grains TAC with a 150 in a Lake City military case.

I'm not sure what velocity it gives. But its very accurate, and it functions all my semi-auto .308 guns.

Remember, if you are using .308 MILITARY brass, the powder volume is enough less, by comparison to commercial .308, that you will see pressure issues with the military brass if you get near the upper levels on powder charge.
 
I would look into AA2495 or VN140 as readily available powders currently. You will likely be off book, but AA4064 would be a good bet also. I have used the first 2, as well as IMR4064 extensively with 150 GR bullets in the .308 win bolt actions with excellent results. These all perform very similarly to H/IMR4895 in this cartridge.

BL-C2, H335, Tac, CFE223 may be worth a try also, with the latter 2 likely to produce best velocity in your 18" barrel. All 4 will be a bit "Blasty".

ETA. Not familiar with the AA ball powders in .308, but big H is showing some pretty impressive velocities in their online data and they have data specific to your bullet for the AA sphericals and AA2495. I've REALLY been impressed with the accuracy of 2495. Outstanding in everything BUT my M1, which was the reason I tried it in the first place LOL. Started with 4 lbs, and have since ordered 16 more even though it's primary purpose didn't pan out. It's just been plain good in almost every suitable and diverse application I've tried. All bets may be off with your shorter barrel though, you'll have to chronograph to see what you actually get. Just remembered an oldie...W748 would be worth a look also.

AR Comp would get the nod for me, it's what I use in my 168gr .308 load for my AR10/LR308. In all honesty, there's a bunch of powders that'll work great. N135 and N140 are pretty available and do VERY well with 150's in .308, I'd be more than happy to run either in a hunting load!
 
Did well with Varget and 150gr hunting pills when I hunted with my .308 AR. Still run it in my FMJ range loads...

I'm transitioning to TAC in my 7.62mm M1a blasting loads... it works well, and is cheaper than IMR3031 or IMR4895.


The standard powder for 150grn .308 autoloader loads is IMR or H4895, and their mates in the same burn range... AA2495, AA2520, VV N135, TAC, W748, BL-C(2). In reality, you can usually step up or step back one powder in that range... so for an alternate to IMR4895, you could use IMR3031 (faster) or IMR4064 (slower) and still be OK. For example, I moved from IMR4895 to IMR3031 for my 150grn blasting loads in my 16" M1a... it worked a little better there, and left my IMR4895 for the Garand. These days, with the (still) limited availability of some powders, having alternates is a good thing. As I mentioned, TAC is working well for me, but so has W748... which is available, and relatively cost effective when compared to the 4895's. AA2495 is another, and seems to be available.

TAC is a good general purpose powder for 223 and 308.
 
Can’t say much for 150’s but I’m using Hornady 168 gr Match BTHP over CFE223 in my AR10. Need an adjustment gas block though to turn down the gas for better cycling.
 
It’s not a hunting bullet but I push 150 FMJ with AR Plus from Shooters World/Lovex. IMR 4064 and TAC also worked, though TAC would need a good load work-up. I’m sure it would shoot, but I just tried the minimum charge which didn’t shoot that great.

2nd that but using the 168 grain Amax. Gassy powder for an AR-10.
 
If that load didn’t shoot so well, I’d scrap it. It requires a different gas setting from all my other loads and going one click too high can give me bent brass rims. Shoots good from my son’s Ruger bolt gun though.
 
I've loaded thousands of 150's and 165's with Varget. I've still got four or five pounds of it, if/when I run out I've got an 8lb jug of 3031, when that runs out I have 16lbs of WC 846. Varget is my go-to for gas guns though.

Tac with a 155 lapua has two distinct nodes in my gun. 42.5 and 43.7. If your shooting mil brass I've only shot the lower node
