6.5-284 Norma

[MSURunner]

Have a decent load with RL26 and the ABLR 142, but looking to maybe back it off a touch and try either a different powder/bullet. I was going to run a ladder with H4381SC on the 142's as well as try some 130 TGK and 127 LRX. Not wanting to burn up a lot of the LRX trying a bunch of different charges/powders, I was hoping someone would have a decent start point with RL26 and H4381SC (or would recommend a different powder). Thanks in advance!

If you get a good load worked up let us know. I am building a 6.5X284 for "F" Class and wanted to use H4381SC with SMK 142s
I also have 123 SMK, 130 STMK, 140 SMK and H4350 ., H4381SC, 6.5 STABALL

My original load development consisted of RL26, H4350, H4831, Staball, and RL23. I shot all of these powders under a 143gr ELDX and for my rifle, RL23 was head and shoulders above the rest in accuracy and was very close to RL26 in velocity. My finished load shoots at 2960fps. I believe it's possible to go over 3000fps with H1000 or Retumbo but that's for others to try. I'm good with where I'm at.

Stabal was a no go?

Staball did better with the 120gr Speer Gold Dot but overall it really did fine with the 143s, just not on par with RL23.

Not sure if this helps, but here's a real time post I did in March of 2020 with Staball and 140gr Speer Gold Dot

For the Hodgdon powders take a look at there Reloading Data Center, it should provide you a good starting point to work on.

Kinda slow. Did ya ever go to 48 like you post mentioned?

I started low as I didn't have any data to go by, and I didn't test any further with the 140. I did go to 50.5gr with the 120gr SGD at 3000fps with good accuracy.

I may have missed it…but bullet were you shooting? Good group.

FWIW, I shoot the same load as 338 but with Lapua brass and a 143 ELDX

I have used both H4350 (47.0 grn) and H4831SC (51.0 grn) with 140 VLD's and the Sierra 142's. Both have shot groups in the 2's and velocity range is 2920-2950 depending on components. 28" Criterion barrel.
