I've wanted to start a dedicated thread for anybody with experience shooting the 338 270gr ELD-X. It does not seem that many people shoot this bullet. Maybe we can dig up some field results.

What cartridge, powder, seating depth, muzzle velocity, etc, are your shooting? How accurately are these bullets shooting and how they are performing on game. How does it compare to other bullets in your gun?

I have been shooting this bullet for about a year now in my 338 RUM. 27" #4 countour 1:10 Hart barrel on a Borden action.

Muzzle velocity with 95gr RL-33 and .010" jump to the lands proven out to be 2855 FPS. One hole accuracy at 100 yards and 1/4 moa accuracy out to 1000. The same accuracy as I'm getting with the Berger 300 EH, but with less temp sensitivity, which I think is from shooting at a bit less pressure.

Finally had a chance to shoot a big bodied bull with this load at 1127 yards. Impact velocity was 1938 fps with 2251 ft.lbs of retained energy (according to the Applied Ballistics app).

I shot the bull 4 times and all 4 shots impact 3-4 inches low with perfect windage. First shot was a complete pass through behind the shoulder through the lungs. 2nd shot was right next to the first and I retrieved that bullet right in the hide on the far side. Bull took a couple steps and quartered hard towards me, the 3rd and 4th shots were maybe 2 inches apart at the shoulder/neck junction and traveled under the heart and into the gut cavity. Neither exited and I did not try and find them. Below is a pic showing impressive bullet performance for a 1938 FPS impact.

I'm curious if anybody has any results with close range/high impact velocity? I would expect high fragmentation similar to the Berger 300 EH.

I think a lot of people are waiting for reports like yours before experimenting. I think the 270 ELD-X is part of a perfect combination with RL26 for the RUM.

I haven't had a chance to kill anything with them yet, but I plan to soon. Here is what I posted earlier on my load development in my new RUM.

I just finished load development in my 338 RUM with the 270 ELD-X. It turns out the 270 ELD-X wanted to jump in my rifle. Things started getting interesting at .100" off the lands and my final testing concluded at .110" off. Additionally, the Fed 215M primer tested out the best in my combination. Here are the final load specs.

270 ELD-X seated to .110" off the lands
87.0 grains RL26
Nosler case
Fed 215M primer
2965 fps

2965fps... that is screaming! Is RL-33 a little too slow for the RUM with the 270gr and lighter bullets?

Is that group you shot at 100 yards? Great to see you are getting top shelf accuracy. Thanks for posting your results here again.

I shot the group at 150 yards. Just my opinion, RL33 is a touch slow for anything less than 300s in the 338 RUM case, but if it's working well for you keep using it.

When I thought of using this bullet I actually thought RL26 would be a perfect powder to get the 270 ELD-X going in the RUM and I believe 2965 fps is a good place to be with this bullet. I was initially expecting and hoping to end up around 2925-2950.

I knew H1000 and Retumbo were always options but I knew I wouldn't get the velocity and I really don't like Retumbo for anything.

Do you have pictures of the bull?
 
By the way these are on clearance at MidwayUSA for $29.28 for 50 and the 230 grainers are the same price for 100.
 
Are y'all finding the advertised BC (G1 .757 / G7 .381) to be accurate?

I generally start with the average of the three BCs provided by Hornady with all the ELD-X and M. The 270 grainer is .747 and .376

Yeah. I stocked up when I felt comfortable committing to the 270. I'll probably get more this week if free shipping pops up.

I'm also curious to hear from others on this. My rifle seems to be shooting them a little higher than advertised. I am going to contact Hornady and ask them this very question.

I've had to increase both my muzzle velocity and BC to tune my load at long range. I have the G7 set at .4 right now and it's shooting true.

Wow. I really need to stretch mine out to see what I come up with.

When tuning/trueing ballistic apps with actual drops sometimes to make it all line up I will have to increase/decrease velocity's and BCs. I think a lot of this comes from the weight of a rifle, bi pod being used, and how much a shooter preloads their bi pod. I tested this once by switching bi pods then shooting for drops. Each bi pod required a different amount of elevation adjustment to hit the center line of my steel plate vertically at 750 yards but not by much. I also noticed the heavier the rifle the more drops matched with the advertised bc and velocity from my chronograph or that it took less tuning from advertised bc's and velocity's chroned. I state this because sometimes it may seem like manufactures aren't advertising an accurate bc for a given bullet but really there is more at play as to why everything might not match up as advertised.
