What’s the word from Starline so far? I don’t have the vertical fractures that you have, but that case separation midway up the body is exactly what I’m getting with 69SMKs through 88ELDMs using CFE. I’ve tried adjusting charge weights up and down during fireforming, and every time I get what I’ve started calling a “speed bump” right where the case eventually separates. I’m really interested in what they have to say.Starline support is working with me thus far. I will keep updated

Sounds like they had a known bad batch of brass (from 2021), so would've hoped they replaced it.That’s some nice CS
If you want a little more OAL, try an ASC stainless 5.56 mag.Loaded up some 69 TMKs with Varget for my 20 inch AR.
27.1 gns of Varget fills the case about half way up the shoulder. 69 TMK seated to mag length are going about 2950 with a single digit SD. Accuracy for a 10 shot group at 100 is just over 5/8.
Rifle length gas with an adjustable gas block and TBAC Dominus suppressor.
Note to self. When you set the OAL with a steel 20 round mag, remember to check that these will still fit in a Magpul plastic mag.
I think the 80 Berger’s would be a better fit but I know some people run the 88 eld’s. I’m sure you could make them work.Out of curiosity, has anyone played/experimented with or found a decent load using the Berger 85.5gn LR Hybrids in 223AI?
There is a decent availability of them local to me and was hoping there may be some experience in terms of starting loads or even optimal loads.
What is the OD of the brass that you fired and did not split?Got the replacements. So far one of the twenty I have fired split in the same way as before. Gonna contact starline again for recommendations.
This is their 5.56 brass. They say they change the metallurgy of the bottom half as compared to their 223rem brass.Have you tried other brands of brass? Is it possible your chamber is oversized? I have run hundreds of starline brass forming into 223ai without issues.

Roughly a 150 FPS MV increase.Guys, I have a 26" 223 bolt gun. Recently got the itch to ream it out and have it improved. Not sure it's worth it though.
What are the benefits aside from gaining a slight more capacity? Will this help minimize case stretch which means less brass trimming?
I’ve got 5-6 firings on this batch of Lapua brass and haven’t needed to trim it yetGuys, I have a 26" 223 bolt gun. Recently got the itch to ream it out and have it improved. Not sure it's worth it though.

How's your PVA barrel treating you? I have one coming soon, too!Here is one of my latest loads developed for a 223AI Tikka T3X. PVA barrel. 24” 1:7 twist
LC brass, Hornady 88 ELDM, 25.4gr CFE223, CCI450, 2.530” OAL. Five shots - 2727fps, ES 8.3, SD 3. .5” group.
Will load up more and see how it performs for 20+ rounds
I’ve got my own project in the works. I can’t speak about the 88eld-M but the std .223 Ackley Imp reamer has a F/B of .0619 so it can seat a 80SMK 2.45 oal.Now I just need to pick a freebore friendly to 75 and 88 eld-m and the cheapo 75 bthp from RMR

I’ve got a uni-throater in 223 and 6mm. I cut to fit my needs.Nice groups!
Did you mail in a dummy round? Chatted up pva on the phone - they said their Ackley reamer has the .062 freebore but they can hand reem to whatever.
Around 2.450”Out of curiosity what is you coal with the 88 ELD-M?
