New Hornady 230gr ELDX 338

I just happen to notice Hornady is offering a 338 230gr ELDX. It is appealing to me since they can be purchased for $40 in a 100ct as opposed to the 285gr ELD at $40 for only 50 of them. I would like to use them in a 338 Lapua Magnum, 32”, 10 twist barrel. The box recommends a 12 twist barrel. Anyone have any feeling if these would even be worth trying in my barrel or have experience with the lighter ~220gr bullets in a 338LM with a 10 twist barrel?

thanks

I'm watching these as well, for a 338 WM that I'm putting together. I think that you'd be in good shape with these projectiles, as long as you can either load them close to the lands or they're jump tolerant. If you CAN run them, I wouldn't be surprised to see 3k+ FPS out of that long of a barrel...

Exactly what I was thinking. I am hoping for over 3000fps from them and comparing them to the 285eld the drop looks very good if I can push them ~300fps faster. They obviously don’t look as good in the wind. I am going to try them at least during barrel break in and fire forming brass. I just can’t find any info on people shooting ~220gr bullets in a 10 twist barrel.
I should have the barrel in two weeks. This barrel will be going in a desert tech SRS

Got out the last weekend when it was a blistering 20 degrees to break in the new 32” barrel.
Decided to use the cheaper 230gr ELDx bullets with H1000 virgin Lapua Brass.
Did not see any signs of pressure ranging from 93.0gr to 97.0gr. I may try and push it up as high as 100gr next time since Hogden’s website has the max listed at 101gr but scares me. Not sure what to do I feel like I’m working in the dark since these are new, not much data out there for them and this is my first time reloading 338 Lapua.
93.0=3022fps
93.5=3047
94.0=3079
94.5=3119
95.9=3098
96.0=3122
96.5=3178
97.0=xxxx
Keep in mind these were only one shot per charge on the magnetospeed.

Damn, that's movin'. I purchased a box of these for the .338WM that I mentioned above, but I haven't loaded them up yet. Seeing your results, I'm hoping to see 2800-ish...

Out curiosity what weight of bullets have you been using in the .338WM and what velocities were you seeing?
I wonder what other people have been seeing for velocities with the 225gr bullets in a 338LM and what powder charges they were using? Can’t seem to find many references. Seems like everyone uses 285-300 grain weights.

I've been running the Berger 250 EH's, but only seeing mid-26xx speeds, with a couple of different powders... from 71-72 grains of H4831 to 74-ish grains of Ramshot MagPro to 69-ish grains of Ramshot Hunter. I just haven't had any luck going any faster (I was originally hoping to see 2800-ish), and I'm starting to see some light ejector swipes at the heavier charges. I'm thinking of trying some of the new IMR 8133, but I'm not holding my breath.

With the new information I've gathered, I'm thinking that 2800-ish with the Hornady 230s may be a more realistic goal, but I just won't know until I get 'em loaded and get to the range.

I ordered a box of Hornady 230gr eld-x in 338WM. Out of a 24" barrel I was getting 2817, 2809, 2806, 2799, 2802. Average of 2806, ES 18.
Box advertised 2810fps.
Factory ammo was loaded with 67.3gn of mystery powder.

BurnOut are you trying to get a 338win mag to shoot over 2800fps with the 230eld-x?
I was originally hoping to see 2800-ish with Berger 250s, but I'm only seeing mid-high 2600s with that projectile... which has led me to purchase a box of the 230 ELD-X projectiles. Based on your MV numbers and the fact that I'm running a 26" barrel to your 24", I'm hoping that I can replicate the speeds that you saw (with the Hornady loaded ammo) with my loads.

I have a variety of powders to try (H4831, Ramshot Hunter, Ramshot MagPro, H4350), and if all else fails, I may see what I can do with some of the new IMR 8311, as it seems to be getting some good results in the Win Mag family of cartridges.

You are going to love the new 230eld-x. I have a few loads that I am working up and for H4350 at 70 I am pushing them at average of 2870fps with ES of 15fps. (Not done playing with that powder yet)
I have startd playing with the RL-19 though and so far I am loading at a compressed load of 78 with no sticky bolt lift. The 230's are flying out at; 2960, 2965, 2958, and 2960 with ES of 7. At 950yards I am holding 6.5mils with a 100yard zero.

Holy shit, NOW you're talkin'. That's the kind of thing that gets me excited to continue tinkering with this thing!

I wanted to try my 78.5 and 79 of RL19 but winter has hit Montana once again so staying inside untill the storm passes. BurnOut keep us posted on your adventure with your 338win and 230eld-x, maybe start a new thread with your build so we don't take over the OP thread.

No worries about posting any and all info on the 230gr ELDx here if you want. It’s new and there’s not much info out there to help others out.

Alright, I give up... how in the name of all that is holy are you getting that much RL19 into a 338WM case? What is your COAL? Even using my (vibratory) brass tumbler to settle the powder in the case, there's not enough room for even 76 gr of RL19 in the case if I want to keep my COAL at 3.43". The internal measurement of the mag I'm using is 3.500, so I have to keep the OAL a few tenths short of that if I want it to feed.

I am using a aluminum rod of about 18" and slowly pour the RL19 in. Every 1/3 of powder I stop and tap the base of the cartrage for a few seconds to settle the powder down even more. When I was loading my last batch of 80gr RL19, and seating the bullet, I know this is the max for this case and the 230eldx bullet. I am using nosler brass 6x fired, trimmed at 2.500" cartridge is at 3.470" COAL, CCI 250 primers. At 79, 79.5 and 80 I am really crunching the powder. But I am pushing it to the max to see what I can do with this round since very little info on the .338win since not many people are interested in playing with this round.

Well, I broke out the crowbar, and got some rounds assembled... COAL with the 230 ELD-X is 3.411, which puts me .010" off the lands in my rifle. I started at 76.0 of RL19 and worked up to 78.0, but I really think that's as much as I'll be able to stuff in the case.

On a side note, I was able to put together a similar 76.0-78.0 RL19 ladder with the Berger 250s at a COAL of 3.435, which leaves me .124"(!) off the lands. I'm still kinda hoping that I can make these work, but if not, it looks like the 230 ELD-X will be a good fall back.

I'm with you regarding the 338WM as a cartridge... not many folks seem to be interested in doing much with it beyond shooting Nosler Partitions at Elk out to 400-ish yards. Don't get me wrong, that's certainly a worthy application of a hunting cartridge, but I really think that it's capable of more than that.
