I have used Re23, 7828 and 4831 SSC.
Good accuracy with all three with 168 VLDs.
The 4831 was anemic.
The 7828 and Re 23 shootalmost identical velocities and accuracy.
I chose the Re 23 due to temp stability as I hunt large temp swings.

2950 fps with Re 23 and Berger 168 VLDs... or 7828. I could likely squeeze more speed out of it, but this is fairly close to the top with my 25" barrel.

Since the Reloader powders are discontinued and 7828 is not currently available, what is the go to 280AI heavy (175 or 180) bullet powder? The more I look around the less I want to sell the RL26 I have.

I load mine with Ramshot Hunter for a 162 gr ELD-X. My buddy has also used Retumbo. The Hunter powder make a very accurate load for me.

I would trade my new, unopened R23 for 1# of R26. Otherwise, my suggestion is grab a pound of VV N565. I’m going to once I run out of other powders. I’ve been absolutely impressed with the N555. It’s the most consistent, tight shooting, low SD powder that I’ve tried in my 6.5 CM. That doesn’t mean N565 will be for a heavy .280AI load, but I’m going to give it a go.

Yes, 7828 probably best. H1000 and R22 will be right in there too. R19 and H4350 are fine powders for .280/.280AI with 140s. I would not choose either for 162-168s, let alone 175-180.

H4831 just flat works, but you’ll be 50+ slower than 7828, H1000, R22/23 most likely.

I forgot to add…. I did end up getting some N555 and love it for the 6.5CM w/ 140s. Slightly… slower than H4350 and just not good for heavies in .280 AI. Pressured out a little over 2,800 with a 162 ELDM. Latest 168ABLR LOAD W/ R23 was 2,920.
