I ended up at 24.9. Took it to 1400 on steel.Crazy....And what charge?
Right on!! Thank youI ended up at 24.9. Took it to 1400 on steel.
I get 3025 fps with H4895, Nammo brass, CCI 450s, and the 75gr ELDM out of a 1-8" 24" Tikka varmint loaded to 2.49" with AICS magazines.
How has 8208xbr compared to h4895 in terms of velocity for you?I will say though....24.9 is a hot load for sure. I've ran this exact test in 20 or more 223 wylde 26" barrels.... anything over 24.5gr H4895 with 75/80gr pulls is hot in a Wylde chamber...
Interested to see your ladder with the 8208. I have 200 80s left and am going to probably ditch them for the 80 smk or 75 eld.I just finished 6 more ladders today...Will post all 8 ladders after I get home and compute the data...I can tell you my rifle definitely prefers the 75s over the 80s. Which is ok with me, cause I can't get any speed out of the 80s anyway...
It's looking like H4895 and the 75 is going to be pretty tits tho...IMR8208XBR also did really well. Matter of fact, IMR4895 and Benchmark also did pretty good. And I was able to get 2900-3000fps from the 75s with all the above powders. 80s are slower than dog shit and I can't seem to break 2850fps with IMR or H4895.
If anyone wants 2 boxes of 80g ELDMs, they're for sale or trade for 75g ELDMs...
This is 8208/75g ELDM since your patiently waiting...I'll get to the others a bit later this evening.Interested to see your ladder with the 8208. I have 200 80s left and am going to probably ditch them for the 80 smk or 75 eld.
Very nice!!I run 75s in my 26” 7.5 twist Bartlein with 25.5 grains of Varget at 3040 fps. My ES sometimes is higher than I’d expect but it shoots so damn good even at distance that I just quit caring about the numbers.
That load killed two rock chucks over 1200 yards last spring. I would never have believed that was possible with “just a 223”.
That is a beautiful rifle and it does shoot!!View attachment 8366722
When I say it shoots, it just flat out shoots. I’m not sure I’ve ever owned a rifle that consistently shoots 10 shot groups in the .5s but this one sure does.

The Nammo brass holds up to it pretty well. I have several firings on some of it. Wish I would have bought more that 1k of it when Powder Valley had it.I will say though....24.9 is a hot load for sure. I've ran this exact test in 20 or more 223 wylde 26" barrels.... anything over 24.5gr H4895 with 75/80gr pulls is hot in a Wylde chamber...
Is Nammo brass military? Never heard of her![]()
Huh, seems pretty cheap. $21/100 for Lapua brass? That seems too good to be true.I believe they make Lapua brass. It is heavier/ thicker than Lapua.![]()

Gotcha. Thanks for the clarification. Still seems like a pretty damn good cheaper alternative to Lapua at 1/3-1/4 of the price anyway.Nammo Group owns/runs Nammo Lapua Oy in Finland that makes Lapua brass along with facilities in multiple other Euro countries like Norway.. Its part of the Nammo Group... From what I have read, NT Nammo Tactical 5.56 brass is not the same as Lapua blue box (223 Rem Match) brass. Its more comparable to Lake City... The tolerances are not as tight as Lapua 223 Rem Match. Still excellent stuff and well worth the great deal I got on it years ago when they were running a sale.

How has 8208xbr compared to h4895 in terms of velocity for you?
Do you shoot varget much with the 75s? Curious what the velocity difference is between h4895 and varget for that bullet. 8208 and h4895 are unobtanium but varget is very prevalent lately.So I havent done a lot of 8208XBR testing in my bolt guns because it shoots so good in my 20" precision AR's with 77smk. I save it for my AR's because I dont need it in my bolt guns with how good both H4895 and Varget shoot. But, I do have a few test targets with 75 BTHP's and 70 RDF's in one of my 26" 1-7 Shilen Select Match bolt gun barrels with 8208.
Looking at the numbers with the 75 BTHP, speed are about 20fps less with 8208 than H4895. So pretty close.

Anything on N540? Looks to get pretty good velocities from the 75s also on their web site. 2956fps with 75 ELDMs from a 25" test barrel. With my 28" 3000-3025fps should be pretty attainable.
I also just ordered a drop tube. I found I was crunching/compressing much anything over 23.5g of powder, which was giving me trouble with getting consistent seating depths...
I mean I get accuracy over velocity and I agree, but there's no reason not to have both, or at least try. Afterall I didn't build this with a 28" barrel to get 24" barrel velocities...I just want 3000fps and 1/4 MOA with the 75s. I don't care what powder does it, as long as I get it.
That's about the same time I bought mine.Nammo Group owns/runs Nammo Lapua Oy in Finland that makes Lapua brass along with facilities in multiple other Euro countries like Norway.. Its part of the Nammo Group... From what I have read, NT Nammo Tactical 5.56 brass is not the same as Lapua blue box (223 Rem Match) brass. Its more comparable to Lake City... The tolerances are not as tight as Lapua 223 Rem Match. Still excellent stuff and well worth the great deal I got on it years ago when they were running a sale. Looking at my receipts, I paid $130 per 1000 for Nammo brass from PV in 2018 ($13 per 100).
my 24" hawk hill got 3k with 75 JLKs and 24.8 varget. super accurate. my 26" proof is around also 3k same charge but 75gr Hornady BTHP3000fps should be pretty easy with the 28" barrel. Mine is a 27"and I get 2960 easily with both Varget and 8208.
IMO that is absolutely hammering with great velocity and an incredible ES for a .223. I wouldn’t touch a thing and run the hell out of it.Got a decent load with 24.7g of N540 and the 75g ELDMs at 2975 fps with an ES of 6 at 10 off the lands. Shooting 1/3 MOA out to 300 yards. Going to do a seating depth test and see if I can't get it to tighten up just a bit more. Going for that 1/4 MOA.
I ran the N540 up to 25.6g at 3085fps but that's about max and hot in my rifle.
After the seating depth testing I'll start making a verified dope chart from 300-1K in 100 yard increments. There's a local 900 yard steel match, PRS style in a couple weeks that I'd like to try and see what I can do with it.
I also got my bolt bushed by Carlsbad on here and it completely took care of my cratering and piercing issue.
Anything on N540? Looks to get pretty good velocities from the 75s also on their web site. 2956fps at 25.8g with the 75 ELDMs from a 25" test barrel. With my 28" 3000-3025fps should be pretty attainable.

Keep a close eye on your brass. Once I got 75 elds past 3,000 fps with 8208 xbr I had a winchester case head separate after 3 or 4 firings. I was seated long too. You'll start to see a ring about the case web about 3/8" up from the rim. I have found winchester 22 lr ammo and center fire brass suck.I use N540 - load for 75's in a 20" and one for 80's in a 26" - I run the first node rather than hot-rodding, both around 24 grains. Both could go 10/10 on a 3" plate @ 465, and on a 10" @ 920, obviously in no wind.

That does seem slow.I also switched to the 75 ELDm from 80Gr.
I am currently at (suppressed)
2820 Average FPS over 27 shots
with first fire lapua brass
Federal 205M primers
set at 1.945 CBTO for .020 off lands and
24.6GR Varget in a 26" proof barrel that now has 125 shots on it.
I was hoping for 2900. I've tested to 24.7gr and dont have pressure but trying to leave space for the blistering heat coming here and i don't really chase velocity too much. I took the rifle to 850 and it's printing well approx 3" at 850 and most vertical dispersion was correlative to the 12.5SD and 44 ES those 27 shots displayed. I'm hoping on second firing on the brass I can tighten up ES/SD. Past 700 hearing/finding hits in heavy mirage is a thing. 700 in is no big deal for audio or visuals.
I put this in a Terminus QC for fun, I never really experimented with 223 and having a great time with it. Did it for the cheaper powder burn and to suffer the wind more and I think the project delivers. I will definitely go with a 28" barrel and order up a fancier one to chase a little more speed down the road but this was reasonable and instantly available suiting the purpose since the range I use it at is 850y.
I compared this to the 25 shots of Nosler 69gr Match which is average 2840 and like 20sd. It was decent but hitting a 6" plate at 850 with it was more like luck, you could really see the different with the eld.
I've got a 18" bbl Tikka, 23.8gr Benchmark will get 75bthps to 2750fps and 73eldms to 2780fps.That does seem slow.
Another shooter at the range with a DMR setup recommended N133 in 223 loads. I would have thought it would be too fast for the heavier bullets, but with a 75 BTHP seated at 2.260", I'm getting 2740 with 22.0 grains out of a 20" AR. The primers look good, and single digit ES over the 3 shots I tested. More testing to follow.
I saw 3000 with 8208 xbr but be careful. Smoked some crappy winchester brass after a few firings.Thanks. Ill have to try another powder sometime so far this thread shows some good recommendations and results!
