Join the contest24”What's the length of the barrel and velocity?
anyone using the 75 eld-m with 8208 xbr?
Hold my beer....I'm getting 2820 with 25.0 grains of varget and 80 eld loaded to 2.480". 24" barrel.
No pressure signs, but do you guys think I'm pushing it a little too much with 25.0 grains?
Friend of mine is running a criterion savage nut barrel on a bighorn. Same results as you and very disappointed.Just to revive this thread... just got a Criterion Rem/age chambered in 223 match. Put it in a trued Remington action (Manners stock,
Triggertech special trigger, Vortex PST gen2 scope... nothing fancy but serviceable stuff). First few rounds while zeroing couldn’t get the rifle to shoot sub MOA. 22.5 grains H4895, 0.050” off the lands. It was running 2750 fps on the Labradar.
I was disappointed bc other Rem/age barrels I had (6Cm, 6xc, 6br) have always shot sub 1/2 MOA, most actually 1/3 MOA or better
Obviously, will start playing w seating depth and may be a tunner. My disappointment is bc this is the second barrel, my friend has another, that doesn’t shoot (I do understand the jury’s out on mine). Wonder if bad barrel lot?... my buddy tried several bullets and couldn’t get it to shoot...
I'm happy to report that I sent the barrel back to Criterion and that their customer service, Michael, is outstanding. They cut a new barrel for me, and it shoots 0.4-0.3 MOA...
My recent experience with the same barrel is the same. I tried the 75 ELDM and 80.5 Berger FB. No matter the powder or seating, I just couldn't get good groups. I switched to 88's and those shoot lights out. I was hoping to shoot something lighter, but I might not be able to.
Are you also running a match chamber? Do you recall when you purchased it? I'm assuming you got it from NSS.
I just bought a replacement for my 2018 Wylde chambered barrel that has been an absolute laser with 55s, 69s, 73s, & 75's.
The neck is 5.15mm=0.2027"Interesting. Some quick back of the napkin math shows that the neck length on .223Rem is ~0.500"
What powder are you running for the 88s? I have a box I was going to try.My recent experience with the same barrel is the same. I tried the 75 ELDM and 80.5 Berger FB.

I have had pretty good luck with 25.0gr of N140 and the 80gr ELD. Right around 3000 fps in a 26". LC brass looks good. Haven't even tested seating depth yet, I believe I'm around 2.49" but dont quote me on that I'll have to check. Ive been loading all kinds of powders and heavy bullets in 223 lately trying to find what I like the best.Both my shooting partner and I are working to find a load with 80 ELDM’s. Both of us settled on a charge weight in the 24.2-24.5 range. But neither of us can get these bullets to run in our .223 bolt guns. I tested out to 0.040” but fount no good group. My rifle has a 28” 7 twist Krieger barrel. His has a 26” barrel.
I tested some 80.5 Berger’s, and they shoot extremely well.
Any ideas?
What powder is this with? That charge range seems to be the sweet spot for multiple people including myself with 8208 XBR.Both my shooting partner and I are working to find a load with 80 ELDM’s.

What bullet were you using? Thanks!Just ran some more of these today Lapua brass 24.5 4895 2.510 oal 26” Bartlein origin action. Run at 2950 my son ran them from 450,600,700,800 1000 with first round hits no problem. This is my backup match rifle.
Yeah definitely have to check and see which do best for you, the 75s are hard to beat unless you get 80s or 88s going quite fast. 200 FPS seems like a lot, for me the difference was around 50-60 FPS between the 75 and 80 ELD.I’m shooting the 75s and I try the 80s. I lost 200 ft./s velocity because of the increased mass and also the longer bearing surface. The velocity loss outweighed the gains in ballistic coefficient.
How did your testing go with RL 15? I have a 24” varmint upper from WOA.Began load development using the 80gr ELD out of my AR15 26" WOA with 1/8 twist and WOA's custom varmint chamber. Using Ramshot TAC with 5.56 data rather than 223 and CCI450. Started at 21.9 grs and .020" off lands or 2.410" produced 1/4 inch group at 200 yards. Hand fed each round.
Working up the charge results were not near as good until I got within 1 gr of max for 5.56 and groups shrank to all touching same hole.
Don't have velocity and SD numbers yet but will retest the loads near max and see if things change.
Plan to try RL15 after retesting best loads with TAC.
Did you find a good load with RL15? I’d love to know. I have the same WO upper as you.

I've had good results using this data with like bullet weights, you may find it helpful.Did you find a good load with RL15? I’d love to know. I have the same WO upper as you. Thanks!
Check midsouthshooters supply. They've had 88s and 75s on sale. They usually have the 80s too.Anyone know of any 80gr ELD bullets in stock? I've checked all my usual places and they are out. I see some at places I've never heard of, but am concerned they are scams.
What is your COAL?24.4 varget. 80 eldm, CCI 400 primer, lapua brass seated .20 off is a hammer for me 2920 out of a 26 inch proof barrel
