26 Nosler / 143 ELD-X / RL-33 / RL-50

[GregShooter]

Has anyone done some load development with the above using RL-33 or RL-50? The Hornady manual does not include any data for 26 Nosler.

Thanks to all!

I had good luck with Rl33 during barrel break-in usings 140 gr vld.
The barrel is back from nitriding and having pressure issues with rl33, however the temp is 15° higher .(60° vs 75°) I'm sure temp sensitivity is partly to blame.
I just got some H50bmg to try. I'll let you know how it goes, it seems to fill the case better but I won't be able to do a load work up till later this week.

How much power did you use of RL 33 during break in?

 

[tbrice23]

I started at 76.0 and worked up to 84 with naked 140 vlds at 60° F.
After nitriding and HBN coated bullets at 75° I stopped at 78.5 gr. Go fugure.

The 70° mark is where I unusually see double based powder show its *** !

How many grains were you using to get 3250 FPS?

If you're somewhat chasing velocity, which we often all are, maybe try some Viht N570.

Haven't loaded the 143 eldx yet but rl50 has been the ticket for me with 140 VLD's. Average group under 1/2 inch and average speed (very consistent) of 3430 fps. 86.6 grains and no pressure signs but I'd work up to that.

Wow...interesting....
26nosler in a 26" nosler patriot...140ab & 142lrab
Rl33..75gr..3200fps
Had worked up and hit pressure at 81.5gr
Loosened primer pocket at 79gr after 2 shots($3 per piece of brass)....
Dropped down to 75 to save brass and hit decent node at 3200fps...and not beating up brass now.....
