223 Lapua Brass neck thickness

[areaone]

Can someone tell me the neck diameter on loaded 223 with Lapua brass. Having a 223 AI built and not sure of the neck for the reamer. Thinking of a .250 for a no turn, will it work with Lapua brass.
Thanks for any information.

My Lapua loaded necks measures .249

Mine is averaging closer to .250" loaded round neck diameter. Works great with my .253" chamber neck, no turn.

this come from a recent barrel for sale on here....

I have a Pac-Nor Stainless Stee,l SuperMatch #4 Barrel Chambered in .223 AI that has been shot less than 200 times...Super Accurate..The barrel is .730 at the muzzle and crowned at 23 inches...Threaded for a Rem. 700....The neck is .2495 and does not require neck turning unless you are using Lapua Brass....Winchester and Lake City Brass require NO neck turning...Just screw it on and start shooting

came from member NCVarhtr post in sale items

You know I forgot to mention: My brass is older brown box.
Sorry

My Lapua rounds are .250. I'd go with a SAAMI minimum .253 chamber neck.

Mine is .2503" give or take a few ten-thousandths. Fairly recent production (within a couple of years).

Ya they should range about .2495-.2501". So your gonna want to go about 252 chamber

Thanks to all, I know I can depend on you guys, saved me from buying Lapua to use in a .250 chamber and being dissappointed.

yes, my .223AI is a .252 neck and with loaded Lapua brass they measure right at .250. Perfect combo and a heck of a cool cartridge.
I went into my project with 3 loaded dummy rounds and the Lapua brass and set it up for that combo along with 75 A-Max.
And with a .252 neck you can always clean up the necks a tad for a loaded round of .249.

I turned my brown box Lapua brass and my loaded round is @ .250 and running 1K tension.
