If this is the one you mean I have one and the ATI .223 magazine has an opening of 2.340" by my calipers. I haven't personally tried a round at that length through it, but it looks like it would handle that.

Stay wellllllllllll away from the proprietary mag attempts. If it isn't an AICS footprint magwell...Run Forrest....Runnnnnnnnnnn.

Avoid AICS poly 223 mags,bask in the MDT version of same and the AccurateMag steel 5rd 223 mags are simply fhuqking sensational. No thang to get past 2.500" COAL there,across the board.



Rather than fhuqk around with proprietary bullschit and if twist/throat/projectile selection were in sync,I'd go a 700 DBM for AR mags. ASC's are very roomy,compared to most and will happily digest COAL's over .300".

6BR with a 105 Smooch from my most recent throat,nestled in a SC Grendel '15 mag. Steel 5rd AICS 308 bindered mag below it,wearing Primal 6BR guts and a few flavors of BC(105 Hornie HPBT,105 RDF,108ELD,etc.) for feed/function warm fuzzies. Of course there were no issues.



Coupla 1000 more words,in regards to same.






A handy/dandy 20" or so boltgun fed same mag system in 1-8" 22 Grendel,would not suck. Nor would a 243 LBC.

Fhuqk that ATI JipJap schit.

Hint.

Thanks, that is the one. I sent them an email last week w/o an answer, so I called yesterday. Gal grabbed some calipers & came up w/ roughly the same measurement. Then Kiff answered my email this AM with a 2 1/4" OAL. Ha ha, is he a machinist or a carpenter?





Comin' through loud and clear, but.....

This for one of my 22-204's loaded to 2.580", which narrows the field somewhat.

I've done several that all feed like schitt through a goose. This prick, I even resorted to pulling the guts out of two of them to try in this gun to no avail. I was likin' the drop-in price tag for the PT&G.

AccurateMag looks like the place to be.....

+++ on the accuratemag. About 30 seconds with a dremil tool & it's right where you want it. I have a MDT that binds like chit, I wouldn't touch another with a 10' pole...

I can get a pic (of top) & a OAL of the accuratemag if needed.

What do you mean by the MDT binding?

The follower tilts and locks up (vises itself between the mag walls, front/back). When this happens there is no upward spring on the rounds & it's like having loose rounds in a cardboard box... Doesn't do it all the time & usually near the end of capacity (3-5 left) but happens enough to make it unusable for my purposes. The accuratemag has been 100%.

My MDT was binding the rounds in a nose down orientation, 30 seconds with a dremel fixed it. If you're having the same problem dremel a little bit of the first "rib".

It sounds like a different issue than what I was having.

30 seconds tweaking a BDL inlet?

I believe he's referring to dremeling the mag insert to increase the COAL it'll take Al.

Thanks Carl, that was 1st thought, hoping for the 2nd, as I thought they were a M5 inlet, correct?

All the mags I saw discussed above (aside from the AR stuff) are of an AICS pattern, and the DBM's for those are most commonly though not always of an M5 footprint.

I run the M5-SA-Stealth in this link for everything:

https://www.stockysstocks.com/acces...-mil-spec-platform-h-p-white-tested.html

It'd require inletting, but wouldn't be too bad as the included pillars will set the Z-axis for you.

PT&G was making a DBM that was a drop in for BDL stocks, but it doesn't take AICS pattern mags due to lack of space.

Also, for conversation, my 6 Dasher rounds are feeding pretty much perfect out of unmolested AICS mags, and 6BR form loads are likewise from Magpul AICS style Pmags.

aalf,

AM's are a nice default,but the MDT Herd Clips are handy fhuqking fhuqkers.(grin)

Have never seen or heard of an issue and we all gun 'em. I shoot them myself,in a Goodly Herd and both in outright DBM bottom metal and integral Chassis,less issue(s). I LOVE them. 223,223AI and 270 all,with nothing shorter than 75 A-Max or longer than Burger 105 High Birds.

Smattering here.





Once set up,everyone shifts gears to drive an MDT poly 10-rounder home,to start things off.(grin)

To add COAL,I tend to depress followers with empty cases and simply whittle what I need,with all staring me in the face. Takes only seconds.



I've never had to touch an MDT or AM interior,to regulate feed/function,other than increase OEM COAL. On my XHCG Chassis 223AI,I did need to whittle the back of MDT mag ribs,in order for them to go into battery and allow ease of the mag latch. A portion of that,is likely due to my penchant to add MUCH spring retention to latches,to preclude dropping a mag on a Cast & Blast.

I doubled up on springs,in the XHCG Chassis,as per it's latch. Also shortened the latch,to reduce leverage,for like reason(s).



KILLER fhuqking set up.

Now as AICS magwell flavored DBM's go,their footprints are all over the map in relative sizing. NONE are lesser than an OEM BDL,due the girth associated with said mags,but some are more svelte than others.

For them on the fly,CDI will inlet your stock for their AICS DBM upon purchase,free of charge. They are fast,friendly and do nice work. Might could well be an option for some.



MDT's are VERY nice to brass.

Hint.(grin)

Settled on a load yet?

Thanks for all the intel....time to digest.....

I'm still fireforming, but I'm 90% complete. If I can make it out to develop a load this week I'll run it in competition next weekend.

I was testing feeding with dummy rounds (formed). Did a lot of fireforming yesterday and was surprised to have BR form loads feed 100% out of my regular AICS mags. They didn't do that in my 700 based 6BR, perhaps the Bighorn is more forgiving...

While I do load work on FF'd brass, I don't trust the best accuracy till they've been shot a 2nd time.



Odd, you'd think it be the other way around on the brass feeding.

Shows ya just never know....

I ran the stealth / mdt in a lvsf stock. The only thing I didn't like was the shelf milled around the metal looks tacky when it doesn't sit flush, but to sit flush the screws would sit well shy of the stock surface.

I just buzzed the rib off the back of the mag and plowed a new lever catch to make it ride high and tight.

That 10 minutes in the mill solved it all.
