Try a different powder if you can, 2206H ideally

The 73 ELDM and the 77tmk were developed for the AR and short mags both shoot well in my Sako as they are a shorter more Stumpy projectile than the 75grn which I have never tried,
Mine still shoots the 77 better than the 73.
I've been told if you are using a button 1-8 barrel it won't stabilize the 80eldm but a cut barrel will.

My Trueflite 1:8 shoots the 75 and 80 grain ELD-M’s very well, so I don’t think it’s a Button vs Cut barrel issue.

That's unusual as my mate had a 1-8 from them and it wouldn't shoot the 80grn was told he needed 1-.
It was him that told me buttoned vs cut but he expects 1/4 to 1/2 moa.

The cold barrel / clean bore shot out of the group, then 5 shots going up in .1g intervals with the 75g ELD-M from the True-Flite 1:8.

This barrel shoots the 80 ELD-M with similar accuracy despite being a 1:8.

62gr ELD-VT showing good promise at 1 one of the charge weights with 0.529 MOA for 5 shots.

75gr ELD-M however, was a different story. 3 different Charge weights, 5 shots each, groups were 1.863/2.041/2.199MOA.

223 Rem,
24 in Barrel, 1:8 twist

0.050" Jump
Benchmark 2 Powder

Im thought maybe they're not stabilising? Although the 77TMKs were fine, and ive shot that load out to 800m

Any ideas on which direction to head next?
Cheers

I would try having a play with your distance from the lands in .010” intervals, then fine tune further once you find something more promising.

Went out this morning for 1 last try with the 75s. Took my lowest charge weight from previously, and seated the bullet all the way to top of bearing surface (about 0.090 off lands).
I think this projectile is just right on the knife edge for twist rate in my barrel. I had 3 shots touching, and the other 2 on the other side of town!

73s on the other hand…….
Just picked a charge weight that put me somewhere in the 51-55k pressure range, seated 0.050, loaded up 10 rounds, and sent them.
Job done

I shot 20 of the 75 gn ELDMs the other night from 3 rifles. Changed powders to IMR 4895 (after shit results with 2219 and something else I don't recall.

Results:



So fairly average results, all 3 rifles 1:8. I really want these to work in a Howa I'm going to chop to 15", and it went not too bad, 9 into 38mm at 100M is about as good as that rifle runs. However there was also that random flier that doubles the group size.

The velocity was quite low, 2600 fps, these should get up to something like 2850 ish at full pressure . . . If I can squeeze the load in, it'll be highly compressed!

Have you tried Leverevolution powder with those 75 gr?

So if stability itself was issue...would you not expect to see yawing??? If not actual keyholing in target???
