338 edge 270eldx r33 seating depth test 300yds

[Timber338]

Not giving up on the 270s ... but they are on a short leash
I might revisit the seating depth around 3.900 in small increments. It's just not normal for the rifle to be finicky. The 300smk, 300berger and 285 testing was easy.

I guess all barrels like what they like. My barrel will not shoot any 250gr bullets worth a darn but it shoots the 270 and 300 Berger EH like a dream. And like you say it's not fussy with those.

Definitely tough to fight a bullet that won't shoot. I have a 30 Nosler that just won't shoot the 212 ELD-X but shoots the 215 Berger great. I'm sure the 212 is a great bullet but I had to move on.

212 is another story. I fought with those in 300wm and finally found a good load. Never looked promising

Don't over look the bullet. I have had no luck getting EDLX of various calibers to shoot in my guns. Other of my friends have had great success but not me. I'm working with them in a 25-06 right now. So far they have taken a sub MOA gun to a pattern that looks like a shotgun. I'm trying to push speed with them with slow burning powders which I am sure has something to do with it. I have also noticed slow burning powders seem to have tighter node spans. Don't know if that's true always or just my experience.

Your not far off, interested to see your end results.

View attachment 156533 Not having any luck with the 270s and r33. Think I'll try another powder cause this combo isn't showing much promise. Base load of 100.5 r33 f215 primers and 3 shots of each coal. It's only 3 shots, but I've tried enough of these to know the rifle doesn't care for this combo. Ideas welcome

5nov19: Update with h1000. 89,90,91 were all together then 92,93 started to climb pretty well.

Hard to see without zooming in but first 6 are grouped fairly well.

This is the second post in a few weeks where you claim a combo is not working yet you refuse to acknowledge that you are do too large of steps on seating depth. That is a fact. .040 is almost guaranteed to be skipping over a seating depth node PERIOD. Do at -10,-20,-30,-40 and then start complaining. As I stated in your other post I have NEVER needed to make such large changes. 60 ish rifles, I dont think I am getting lucky.

The reason I said the combo isn't working is, nothing so far has shown me promise. All my other rifles showed some accuracy with a combo. Like I said before, the 300smk Berger and 285s showed accuracy with base loads.

Not refusing to acknowledge anything. I already had them loaded up and ready. You would do .010" increments from the start? That is a ton of rounds down the barrel if they don't work. Makes sense to me to do a macro test then narrow down. Berger does the same thing.

Despite being a coarsely conducted ladder test, I think it was successful. I see very little vertical in the first few powder charges with a decent group in the center of the target. It looks to me like the 270 ELD-X is shooting pretty well around that 90 grain area.

Definitely coarse for the first test. Shows some promise now so I'll zoom in on the 90+/- area

I have a very accurate 300 wm that won't shoot the 212s either. Eats everything else quite well.

Interesting. I wonder if Hornady is having process control/quality issues between lots or at ends of production runs. Luckily all of my 270gr ELD-X bullets are from the same lot.

One thing I did notice with my 30 Nos is it also shoots the 210gr Accubond Long Range very well, and it shares a similar length bearing surface as the 215 Berger while the 212 ELD-X is much longer than the other two. I think it's changing the initial pressure spike and resulting harmonic. Might need a drastically different seating depth sweet spot that I skipped over.

I have not measured the bearing surface on the 338 270gr ELD-X and how it measures up to the 285 ELD-M or the 300 Berger EH. Might be an interesting comparison.

Did you make any changes to the scope with the last 3 rounds? because the high shot looked like a flyer. But then the next 2 were up there as well. One thing that i learned a long time ago while i was drag racing is you only change one thing at a time.That way is if works you know what was wrong.Because you went from 300 hundred yards to 5 hundred.that makes a differance.

Scope setting was on 1.4 mil the whole time. Try to do my ladders at 500 and seating depth at 300. Many ways to do it, but it works well at my range the way its setup.

I haven't had a bullet yet that wouldn't shoot between 5 in and 40 off. I seat them all 5 in and bring my arbor press and start working my way back. Seating depth comes together and opens up like powder. If it isn't 3-10 off then I jump to 20 and work back .005 at a time.
