300 Win Mag ELD-X load testing?

[raven1776]

I have 200g ELD-X for my wife's 300wm. Was reloading it with RL23 but cant seem to find my data. Anybody used this combo with any luck?
Any known data would help.

pull one apart and weigh the powder charge and check C.O.L before pulling one apart

I'm looking to go out to 1000yards. Which is why I choose the 200gr. I was looking at the heavier rounds but I want to see how the 200 work out to 1000, I just have to close the group in from 1.5" moa, the 178 are shootin about .2"-.3"

What's the avg fps you guys go for in 200? I was thinking maybe like 2700

Can you share that 178gr insight for me brother.

I use the 220 ELD-X in my 300RUM. I been running RL26 and seating the 220 at about the max magazine length that feeds well in my Sendero. I think its at 3.65. I get 3025fps. They shot .5 to .6 MOA at 200 yards. Made a kill on a deer 2 years back at 761 yards. I may looks at H1000 as well this year as a backup load.

I tested this load at 200yrd and this was my best group with it. (pic attached). The other groups varied from about 1.9"-1".

178gr ELD-M
Hornady Brass
Fed 215m Primer
74.6gr of RL-26
Seated at 2.844"

rifle: R700 Long Range 300WM, 26" barrel, twist 1:10, aftermarket Schuler brake installed, Timney 510 trigger.

(I haven't gotten to deep into reloading, I only clean primer pocket, Full Length Size, and deburr the neck. I dont get into the fancy or intricate stuff yet...)

Is that a typo on 2.844 COL? Seems a bit short

since the tips of the bullets can vary I use the measurement from the Ogive, makes more consistent measurement.

when I was measuring from tip to base it was 3.500" was the magic number, but when i changed to measuring from the Ogive, the measurements of the loaded rounds skewed greatly.

 

[ncwg2boatguy]

Gotcha. Using hornady kit?

 

[Dune870demon]

yes

 

[ncwg2boatguy]

So RL26 is that the same as 25 but more temp stable like 22&23

No. It has a slower burn rate than Reloder 26, despite what the number suggests.
Also Reloder 22 is NOT temp stable.

 

[Dune870demon]

26 is supposed to be a split down the middle between 33 and 22.

That covers a lot of ground.
That has got to be the most vague description of a product ever. And that is exactly how Alliant billed it when it was released .
