Do you shoot your .223?

I could be doing something wrong. Typically I need to trim about every 2-3 firings but maybe it is the factory chambers/actions. The new build I pictured above has a custom action and barrel and should hold the case better.
I didn't mean to imply you were doing something wrong, if it works for you, then it works. If an Ackley chamber means you don't have to trim as much, and you get more velocity, that's even better. Different brass/loads/chambers/dies can certainly yield different results. I'm just surprised you're having to trim that often.
Okay thanks for that. I’m thinking that for the next barrel I’m going with a 26” heavy varmint or medium Palma profile. But it will be 26” to ring out a few extra FPS. Based on your points above the only down side I can see is needing to buy another set of dies. I usually shoot my 223 within 600m-700m with 80gn Berger Full Bore projectiles, some more horse power May not be a bad thing.
To be fair, I don't take a lot off when I trim. My trimmer is set for 1.755 so it doesn't have to do a lot of work. The brass probably grows .01-.03 per firing/sizing.
Also, isn't Federal brass short out of the box? I've experienced some brass in the past as short as 1.740, and I thought it was FC headstamp?
I'm sure my Lake City-produced FC brass is shorter new than what they are now, but I don't have measurements for what they were new. I just check them in my chamber stub-gauge (cut with the same reamer as the chamber). If the cases are too close to the chamfer at the end of the chamber, I'll trim, otherwise I won't worry about .010" since it won't improve my scores at the local steel matches. Shooting a .223 Rem there is already a handicap. 
Put another one together. Still finding a good load.
Just curious, are you using the Accurate 5 rnds magazine or is it the new MDT 223 DSSF mag https://www.thefirearmblog.com/blog/2021/08/02/mdt-10-round-223-metal-aics-magazine/

Do they fit long loaded rounds like the mdt? I have some loads I picked up that fit the MDT but not the accurate
I really enjoy my 223 trainer. When we first got into prs, we all bought suppressors. Then everybody switched to brakes so my can just can. Built a 223 and screwed that baby on there. I find it surprisingly pleasant bc u still have to manage recoil and it’s suppressed. I’ve also been able to shoot some of our local matches with it and have done quite well. Out past 800 I don’t expect much bet anything inside 600 im still very competitive

I shoot mine all the time for training. Saves powder cheaper components that are actually available. With the 80 eldms the dope is pretty similar to my match rifle. Great barrel life cheep to shoot what’s not to like!
Clever design. AW like presentation of the top round (except always left side). Not often something actually innovative in magazine design - at a nice price point to boot. Good for Magpul.
What issues have you had with the 10rd accurates. Those are the only ones I’ve seen that haven’t had any issues during comps. I’ve also got 5 of them and unknown how many rounds have been put through them with no issues.
For loading long, just file the front out
I feel like this topic has come up a bunch lately, especially with the scarcity of ammo and components. I have had a 223 precision rig for years now, and the more I shoot it, the more I enjoy it. Inside its respectable distance, it does everything else my other calibers do. I like 223 because it doesn't burn up as much powder as my different calibers. Also, I do not have to worry about my family coming out shooting with me and blowing through all my expensive match ammo. My wife also really appreciates the lack of recoil and enjoyability it is to shoot vs. other calibers. It's an all-around fun and practical caliber in a bolt gun. I think everyone should have one! Plus, after a day of shooting 6.5, you strap a can on the 223 and start plinking steel; it turns into a downright giggle gun; a heavy 223 has absolutely no recoil to it.

Sounds more like that mag isn’t sitting high enough. Close your bolt and see if you can push up on the bottom of the mag.
I wonder if these can be modified to load a little long like their poly magazines? I would like to see a picture of one from the top.
Any experience on the 75bthp vs the 75 eldm?
All I have ever shot is the eldm and was thinking of giving the bthp a whirl.
That’s why I love my SAC desert tech magazine. I think I can load to 2.550. My longest load is 2.535” 80 ELDM ON SAC REM match chamber. Absolute pleasure to shoot.
I know I modified my 5 rnd Accurate Arms 223 AICS quite a bit for proper 300 blk heavy subsonic feeding - not sure what the max coal would be if you take the whole front plastic plate away.
It’s a decent mag once you’ve tuned it. Out of the box it’s quite mediocre.
Overall I’ve always felt like the current offerings were lacking - hope the new MDT DSSF resolves the issues of the earlier plastic AICS 223.
Every barrel I've had has grouped better with the 75 BTHP versus the ELD-M, though my current barrel absolutely loves the ELD-M. Main downside is the worse BC and more wind drift.
Same here with SMK 80/Scenar 77. They group slightly better than the eldm 75 and 80 until 600- 800 yards depending on the wind then the eldm do little bit better due to the better BC
I reload so I have boxes of 223 for the bolt rifle. Those loads, with appropriate bullets for the task, are proven accurate in that rifle and separate from the FMJ reloads that the AR likes.
My last Bartlein barrel shot 75 ELDMs so well I stocked up on several thousand. The next barrel wouldn’t group them no matter what I tried. Was about to give up on the barrel till I gave the 80 SMKs a try. The 80s shot every bit as well as the ELDMs in the previous barrel.
As they say, feed it what it likes.

How did I miss this? Did you get some and use them? My mdt plastic mags work "ok" but not great.
I love my 223. It's such a pleasure to shoot suppressed and it's such a hammer.... what's not to like?

probabily not as much as I should but I still love them just as much as all the other guns that I own I do have a special place for all my bolt guns as well as my poor gas guns shame they had to go hide out for a while , but as It's for there own safety It's all good . And I still want a shorty bolt gun in 308 , like a little puppy the idea is just following me around .
I run an 223ai and will never go without one at this point. It's my go to fun setup for range use and/or hunting. Currently running 80gr eld at 2950fps which duplicates my 6mm bra 110gr load dope out to 650ish.
Have you tried Varget? I tested some 8208 and it did really good but the Varget was better for group size. The 8208 was still at half moa area though and velocity for both was right where I wanted them in the 2940-50fps area.
How much Varget are you dumping? I’ve gone up to 25.5gr(3000fps)with a 77 Nosler CC with hardly any pressure but they’re compressed pretty hard.
Would have to check my book but it was in the 24.5 range if memory serves. Running a 27” barrel. Oal is also about 2.470”.
There was a small amount of primer flow but that’s it, it was almost 90* when I tested them too. Even more surprising is I was loading 2.26” since my chamber is kinda short.
Hmmm, you’re faster with a heavier bullet and way less powder. I got a 26”. I originally loaded only to 25gr because I thought I would hit pressure before then but didn’t. Don’t think I’ll push it anymore, just way too compressed.
I get getter accuracy out of the 75gr BTHP then the ELD-M. I've only tried it with N140 powder though.
Someone just gave me a box of 75gr ELD-M recently, as they discovered it was too long for their AR15 magazines, and they don't want to single load. Will try the bullets again, but with a different powder.
