223 80 ELD-M Load

[Chickentoast]

Just received a box of 80 ELD-M's to try in my Savage Stealth Evo, 20", 1:9 twist. Hoping they'll stabilize...

Current load is 75 ELD-M
COAL 2.388
N140 23.7 gr

What are you guys running for the 80's? I'm thinking of leaving the COAL as is, which for me is 20 off, and pulling the charge down a bit due to the increased pressure in the case. Probably try 203b and rl-16 as well, if anyone has data for those. Any input appreciated.

I'm still playing with the 75s with 24.7gr of varget(25.1 was all the cc400 primer wanted)and they're running 2.541 jumping .020 in an axis with a 7 twist. I would love to know the freebore on his thing. I've measured berger 80s and they were within .010 of the same coal. I have a box of 80 elds and I bet they will be over 2.6.

That's a long throat for sure! 75's are fine for me out to 1K without wind. Want to run 75's and 80's back to back and see the differences, assuming I can stabilize the 80's.

2.4 coal and 24.4 203b worked for me, and I got them out to 900 yds without issue. At 460 yds, was hitting 3" steel 2-3 times in a row, and 4" steel every time, w/ 0.4 mils wind.

Both my shooting partner and I had a difficult time with the 80 ELD. I am running a 28" 1:7.5 223 Match chamber (.080 FB). I found a velocity node at 24.7 Gn Varget, but could not get a group less than half-inch to save my life. I had some 80.5 Berger Full Bore projectiles sitting around. My first group with them was easily 3/8ths maybe less (5 shots). Sold the ELDs the next day. I don't think it was a bullet issue, I think it was an issue of me asking too much with too little free bore.

The 80.5's are running in the high 2800- low 2900 range. They hammer.

I have a long freebore 223 and am loading mine 24.8gr shooters world precision at 2.52" oal with a 1:7 twist

I have some 80 vld Berger's also since the eld-m's dried up, but no Full Bores. Will have to work up another load... I was able to get under 1/2" @ 200 out of the 80 eld-m's, so I agree it was likely the coal holding you back.

It was a bummer, I had a thousand of them before I even received the barrel. I considered having it throated, but was concerned with concentricity issues associated with that process. One smith I talked with was ok with the thought, the other was adamant that he would not throat. (Again, referencing a specific tool for throating, not a reamer)

Didn't know throating a chambered barrel was an issue. We keep getting new cartridges developed that re-invent the wheel, instead of simple throating guidelines (or new reamer specs) to take advantage of new bullets and powders. I'm fairly certain I can find an existing case that works for almost any velocity I want to run... the only (sometimes) consideration is COAL vs action / magazine length.
