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.This must have to do with people's reloading equipment or process. I have a set of no-frills Federal .223 rem brass thave I've reloaded 15 times. Cases are at ~1.760"OAL, but still .010" short of the chamber length. I generally just use a Lee collet neck-sizer, and I've only FL sized them once and have never trimmed them. They chamber/extract my bolt-action as new; zero effort. The load is a solid 1.5gr over book max (77SMK at 2935fps from 24" barrel), primer pockets are still as tight as ever. Makes me wonder what people're doing to require frequent trimming.
I like 223AI but it isn't for everyone. It gives me another 100+ FPS out of a 22" barrel, which really shows at distances beyond 600. Fireforming is easy, just shoot 223, and accuracy is pretty close to the real thing so you can play on steel. The biggest thing I like is that I don't have to keep trimmming the brass once formed like you do with 223.
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.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.
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/

Magpul just released their 10rd polymer mags.accurate but you just cost me some money
Do they fit long loaded rounds like the mdt? I have some loads I picked up that fit the MDT but not the accurateMagpul just released their 10rd polymer mags.
Not sure how long the MDT is, magpul says 2.39” oal.Do they fit long loaded rounds like the mdt? I have some loads I picked up that fit the MDT but not the accurate
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.Magpul just released their 10rd polymer mags.
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.Accurate 5 rd mags are outstanding but their 10rd mags are not as reliable.
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.The 10 rd accurate mag I have will not feed reliably if I load it with more than 5 rds.The bolt will sometimes run over the round and not chamber at all.
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.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/
Any experience on the 75bthp vs the 75 eldm?I'm not a huge fan of Sierra's bullets. I think they want too much money for them. The way the Hornady 75 BTHP shoots I can't see spending the extra money for a Sierra bullet. I paid 14 cents a bullet for the Hornadys.
Just another 223 mag that will not accept cartridges loaded with 80 grain bullets for a Wylde or similar chamber.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.

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.Just another 223 mag that will not accept cartridges loaded with 80 grain bullets for a Wylde or similar chamber.
Any experience on the 75bthp vs the 75 eldm?
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 BCEvery 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.
I bought a bulk pack of 75 eldms thinking I was going to primarily shoot those but I've barely used them because they just don't shoot as well as the BTHPs. They have a real pointy nose so they're probably the type of bullet that would do better with over .100" jump but the irony is that if you stick them that far back in the case they're going to be eating up powder capacity

How did I miss this? Did you get some and use them? My mdt plastic mags work "ok" but not great.accurate but you just cost me some money
Same here. 0.015 off the lands.I load the 75 ELD-Ms for my Tac .223 and load them .020" off the lands and they shoot great. What powder you been using?
I love the 80 SMK. Super forgiving and easy to load.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.
8208
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.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.

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.25.5 is hot with 77 gr. I’ve blown primers at 25.3 on a really hot 100+ F day.
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.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”.
Ah, confused you for the guy shooting 80s. I’ve only tested Norma brass.I am using a 75 ELD so actually lighter than your bullet. Brass would also make a difference. I am using Hornady brass.
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.
