25 Creedmoor - Best of the Creeds?
- Thread starter Towhead
- Start date
thanks for the replies and data
I'm going to use a 22" proof or PVA carbon fiber (suppressed) and looking for 2850ish with the 134 ELDm and H4350. SRP brass, undecided on Peterson or alpha.
Sounds like i should be able to get that with the ole reliable 41-42gr range of 4350

I think it depends on a few different factors but I’ve seen quite a bit of different data points while researching the cartridge. Kinda hard when it was a “wildcat” and no SAAMI reamer specs to nail down general load data.
Umm it's still not SAAMI spec as far as I know however Hornady is already making brass so I assume they are planning to.
You might get it with a different power but I'm very skeptical you can get to an all weather condition load with that speed but let us know what you actually get once you build one.
Yeah it’s not a SAAMI cartridge yet but seems the common thought is that it will be. I already built one and am just breaking it in. My specs are a few posts back.
I've chambered three 25 Creeds in the last month for myself and local PRS guys. All three of us are running Alpha SRP brass and 134 ELD-M's between 2850 and 2880 with H4350 with 26" Brux MTU's. The reamer I'm using is optimized for the ELD-M to have the boattail / bearing surface junction right where it needs to be for max case capacity. I hit pressure above 2900 on my rifle so I run at 2850 pretty comfortably with 41.2 grains for H4350. Accuracy is absolutely spectacular. I shot my personal smallest three shot group measuring .0395" with all groups for that final day of tuning falling under .25" Round count so far is just shy of 600 rounds - the Alpha brass is on its 5th firing and primer pockets are still nice and tight.
We all expected to easily reach 2900+ with this cartridge and it is possible with the 26" + barrels but your gonna torch your brass early and it just isn't necessary. This thing rings steel at a mile with ease.

.2915 Neck / .145 FB
I went through a few different iterations of reamer design and landed on this one. Its been a hammer so far.
.258 freebore is waaaaaaaay too much.
My JGS BJ reamer has .115" FB which I played with a bit, but it was a little short for the 134's. .140" is about perfect for 134 ELD-M's.
Only Varget.
I pushed them faster on 10/5/24.
Mild extractor ring on the brass. Probably maxed out. I have not had any vaporize. I think the VMAX are ok. More ELD-M bullets come apart in my experience. 6.5 PRC anyway.

Yeah but 133 Berger still better ballistically it seems.
.283 bushing
I did the measurements and math and even tried .285 based on that but .283 for Lapua and Alpha brass seems perfect.
Anyone have load data for the 25 CM and Nosler 85 Ballistic Tip? I’m afraid my barrel has too much freebore to run 75 VMAXs so looking to shoot a longer bullet. Looking at the burn rate charts, CFE223 might be a good match if Varget pairs nicely with the 75 Vmax?
Anyone have at least a starting point for an 85 ballistic tip in 25 Creed? May try the Varget I bought or CFE223. I do have some Superformance laying around too. I'm just too new to reloading to know much more than heavier bullets generally = slower burn powder haha
@Ledzep fingers crossed you guys are working on a 90 ELD VT!

Maybe try the 134 eldm.
I have a 22" proof barrel with 155 rounds on it now. Using Alpha brass, CCI 450, H4350 and 134 eldm .50 off the lands, i am getting 2785 fps with 41.5 gr.
I was getting 2830 fps with 42.5gr about 75 rounds ago. Going to do a ladder test now that the barrel has sped up a little.
I would expect your longer barrel to get some more speed over what i am getting. How many rounds on your barrel?
well, my only suggestion would be to try CCI450 and some alpha brass, if you're not using that already.
I'd also think the 134 ELDM would get you closer to power factor since you are on the razors edge.
Only need 2836 fps with the ELDM vs needing 2857 FPS with the bergers. That 1 gr makes a big difference in your case.
11 fps seems doable, but idk about 30+ fps
power factor for NRL? Can’t get h4350 to work for you, try a different powder. Superformance gives a noticeable velocity increases without an increase in pressure. Its tolerance to temperature is not bad. In my days of shooting 6.5CM, I was getting a good 100 to 150 FPS increase in velocity over H4350, good loading density, single digit SD’s and accuracy that has never been achieved in any other rifle.
These 25 Creeds just shoot. Alpha brass,134gr eldm, H4350 on a Aero Solus. Need a touch more powder to get 2850 fps
8 shots if you include the sighter on bottom left. This is a used barrel with 600 rounds down it.

I believe I will eventually desire one. However, it would probably be more of a dual-purpose competition rifle (PRS and NRL Hunter) than a hunting rifle. In terms of a hunting rifle, I don't see anything it can accomplish that other cartridges couldn't do better. When it comes to big game, I prefer magnums. That's kind of what I live for, but I don't see how a guy could go wrong with a new gun in a different cartridge.
