What powder for 6.5 prc?

[theddguide]

Looking to start loading for my new rifle. Just looking for recommendations on powder for 140gr bullets. I have a good supply of h4831sc, a couple pounds of h1000, and a few lbs of retumbo. Barrel is 20in, which is making me wonder if h1000 or retumbo would produce as well compared to h4831sc. Thoughts?

Also have a bunch of 7828ssc but would rather use something that is temp stable.

57 gr of H1000 behind a 140 ELD-M for me.

I'm using H4831SC with great results in a 21" barrel, though I'm shooting 124gr Hammers not 140 class stuff. I'll stick with it until I can find some RL26.

Both powders you have should work, I would start with the SC, I personally use N565 with 156 Bergers
