280 ackley improved propellant (need advice)

[Joshlee9986]

I am about to bring home a 280 ai on a rem 709 action with a 24 inch barrel. I was planning to shoot 162gr ELD-X and 160gr accubonds. I need a temp stable powder due to crazy temp shifts here. Trying to get good velocities out of it as well. What's the "go to" 280 ai powder? I apologize if this has been asked 1000 times. I do appreciate any advice!

H4831,h1000

rl 23 will get you great velocity if your rifle likes it h 4831 always works but is a little slow in velocity

Mine likes H-4831 and Reloder 22 best

If you want temp stable, I'd look at H4831 and Re-23.

RL23

Another vote for H4831 (or H4831SC) here. With the Berger 168 vld's, Nosler brass and Federal 210's mine regularly shoots half moa or better at 200 yards. Velocity on the load is a mild 2830-2840 fps, but is consistently accurate.

RL23, get you some Peterson brass also.

I'll be the oddball....H4350 or RL16 with that barrel length and bullet weight... you won't be giving up much, to very little in velocity. Temp stability will be on par as well.

 

[L.Sherm]

RL23 is very stable.

H1000 is the most temp stable. Temp stability in my test has gone as such:
From 80F to 0F @8000ft elev.
Hodg 10-25FPS
IMR Enduron 40-60FPS
Reliant 70-100FPS

 

[Caveman0101]

I've also tested several that are not advertized as temp stabile in: Accurate, Hodg, Norma, RL, IMR,
They where all 100fps+ with Norma MRP being the worst.
Forgot I tested Ramshot Magnum also.

Did you test any of the Alliant that are advertised as temp stable?

I agree. I fought H4831 SC endlessly. H4350 was an instant success.
