Hornady 30 Cal .308 178 gr ELD-X

This is a discussion on Hornady 30 Cal .308 178 gr ELD-X within the Ammunition forums, part of the M14 M1A Forum category; I think this weekend I'll be trying some of these handloads out. I'll post results if that happens....

Got mine yesterday. Sending 25 off to Copper Creek for a loading ladder.

So could the 178 be ran in an m1a? Thinking this could be a good yote, deer and target bullet

Of course but it was designed for hunting deer and elk. Better for yotes would be a 110 grain round.

Also for target shooting the FGM 175 SMKs (and 168s) are much less expensive, those are designed for target shooting and not for game.

I have my 25 rounds of Copper creek loaded Hornady brass, 4064 powder, and Hornady ELD-X 178 bullets. Going to shoot for several days straight to get my accuracy back, then going to shoot 4 rounds of each loading. The most accurate group will then have the bullet and powder removed from the 5th loaded round and I will weigh the powder. That will be my formula for loading.

I measured a lot of the bullets, they were all either 178.0 or 177.9 grams. But the new Hornady brass swings from 164.1 to 166.2 grams.

I shot 20 through my bolt rifle the other day from 41.0 -41.8gr of 4064. 41.8 returned a group smaller than a quarter. Gonna push em up to 42.5 and hope they land there as thats the same load I shoot in my M1A and other Remmy 700.

So, I went to the range today to try some of these 200gr ELD-X's as well as some other hand loads through my Model 70. The darn ELD-X's wouldn't chamber! I set them to 2.800" COAL as recommended on Hornady's reload table. Apparently that aint right. My M70 loves 175gr SMK's set to 2.800" COAL. I know its my fault for not checking before-hand, but dang. I figured the standard COAL would be fine to start with. At least today wasn't a complete wash. I found the optimal (for now) load for my rifle:

5 shot group @ 100 yards, 50 degrees, overcast. Humidity 65%.
175gr SMK
42.0 gr IMR 4064
WLR primer
RP Brass full length resized and trimmed to 2.005"
COAL 2.800"
(Gun: M70 HBV .308, 26" bbl, 1:12 twist)


Thanks from breastroker and WaM14gunner

Now that's a nice group even for 175 SMKs.

Thanks from twobyfour

I've read three different articles about the Hornady ELD-X program. Seems they had doppler radar setup (a first for them for bullet testing). What they found was that after three hundred yards the BC began to change, and the bullet experienced more drag. No ifs ands or buts about it as doppler results are pure numbers and they don't lie. They tested other manufacturer's bullets with the same or very similar results. The tips were softening and changing shape after 300 yards.
Additionally, there is a whole separate benefit with these bullets and that is the mushrooming will occur at a wide velocity spread. In other words they'll mushroom at 50 yards and they'll mushroom at 900.

Recall?

If Hornady is correct about melting tips, why have they not recalled all previous tipped bullets? I have asked this question to Hornady twice with no response

Thanks from jaholder

Hornady response

"There is no defect, the bullets will still shoot as well as always we have just improved the certain bullets in some calibers that have B.C.’s that keep a bullet within a heat range that could make the previously used tip soft"
In announcing the ELD they noted "Further testing was done to confirm suspicions that the polymer tip was the culprit. Aerodynamically efficient, high BC bullets at high velocity were suffering from polymer tips softening and deforming in flight. Further testing proved that it happens to all conventional polymer tipped bullets, regardless of manufacturer. Tipped varmint bullets and conventional low to medium BC (sub .550 G1) bullets are not significantly affected. They simply do not hold a high velocity long enough for the aerodynamic heating to significantly affect their tip."
So I guess that after talking about "soft tips" they decided they are not really a problem. I wonder because if you have the same bullet in a 7.62X51 or a .30-378 Weatherby the velocity is vastly different.

Anybody ever figure out a good load for these? Ive tried 42 and 42.5 and they are all over the place. Thinking about pushing em a little faster out of my 1:10 bolt rifle to see if it helps.
