RL 26 / 200 ELD-X for 300 Win Mag

[TackDriver284]

Seeking to work up RL26 / 200 ELD-X and this powder is not listed in the Nosler manual, only found not much data on the Alliant website as 74 grains / 200 ELD-X but I expected more data.
Would anyone have any data on the RL26?
I have RL26, H1000 and H4831,,,,which powders would you choose if you had experience with those powders. Thanks

Thanks Mike, seems case fill is just perfect with RL26 with 98% and 110% for the H1000, maybe a drop tube will help settle it.

 

[DrMike]

I doubt that you'll need a drop tube with either propellant. I readily get 110% fill on a variety of cases. You'll definitely get a good velocity.

Tried the 200 ELDX on one moose with H4831.
Too much expansion and meat damage very similar to Ballistic Tips ……quickly purged my whole shelf of ELDX. The 178gr ELDX might perform well at 308 Win vel maybe but I am done with Hornady rifle bullets ! I think they need to apply some their DGX technology to their others bullets.

You are correct that the ELD-X is frangible in the 300 Win Mag. On my last hunt with the 300 Mag, I used the 200 ELD-X on two cow nilgai, I tested one cow with double lung shot, complete pass through, no bullet recovery and the 2nd nilgai was broadside and it shattered the shoulder, and destroyed the lungs and did not leave a mark on the inside opposite shoulder. Seemed that the ELD X broke apart after the hit on the shoulder bone. Velocity was a hair short of 3100 fps with RL-26. I stopped using the ELD X bullets for the 300 Win Mag for this reason if hunting medium to large game, I am switching back to the 180 Accubonds, I'll look into the 200 AccuBond as well.
ELD X may be fine for slower velocity like the 6.5 Creed and 6.5 x 284 using the 143 ELDX and 308 using the 178 ELDX. I have 40 rounds loaded up for the 6.5 x 284, speed is right at 2910 fps with the 143 ELD-X with H4831SC.
