Criterion 223 Remington match chamber

[EODsniper]

Looking at a criterion prefit shouldered barrel for a Zermatt action chambered in 223 Remington match with a 1:7 twist. It will be fed from mdt .223 aics mags. My question is will this chamber shoot 69gr/
77gr SMK loaded at 2.26” just fine with the .090” freebore? I also intend to shoot heavier reloads which is why I am leaning towards the match chamber vs the Wylde. Anyone have experience with this?

The smk are supposed to be jump tolerant but the longer match freebore is nicer if you handload. For factory only I don’t see an advantage over the wylde.

I have had two criterion 223 rem match chamber barrels

My COAL's with bullet jammed for my new one are.

berger 75vld 2.473
berger 80vld 2.464


In my old barrel I have shot probably a dozen different bullets from 69 to 80 and have had good
accuracy.

77 Sierra MK bullets are designed for a AR15 magazine there are way better bullets for a
bolt action rifle.

Yeah I get that there’s better but I have a large stockpile of 77gr so was just curious

I used to have a criterion 223 barrel with their match chamber and it shot 77 SMKs very well

my plan is once I shoot all my ADI 69gr SMK and federal 77gr is to reload that brass using 80gr SMK or bergers

I’ve been getting mine dialed in and it eat the 73gr GMM like a champ while throwing rounds through it before going to deep into load development with a fresh barrel. I’ve even run hornady 55 fmj’s through it with pretty good results considering the jump they are doing.

The couple powder charges I’ve run through it with 75 ELD-M’s have been pretty solid, not exactly to my standards (I’m used to the easy button 6BR stuff) but the barrel had less then 100 rounds through it at that point.

That’s good to hear. My main concern was basically getting a barrel that wouldn’t allow me to use factory ammo but from the sounds of it there is no issue whatsoever. The only deciding factor is that having criterion make a Wylde chambered barrel is a 18 week lead time and northland has the 223 rem match in stock. I have a Krieger 6arc barrel in another bolt gun and 220 rounds is where it finally shrank groups and sped up about 60-75 fps. Everything has still been less than an inch but now we are getting cloverleaf groups. Time to start the handloads.

Northland is a great company to deal with and they keep a good variety of stuff on the shelf. I wanted a bull contour in 24” but didn’t want the lead time, so I called up northland and had a 26” to my door in under a week.

Anyone have a print for this chamber by chance?

.223 Rem match chamber?

Does the 223 Rem match chamber require neck turning? Mike

Thanks, I have seen that one before. Just wondering if it's a "universal " reamer for the match chamber.

There is no universal reamer for anything “match”
There isn’t even a definition of what match means.

I agree, guess the only way to know for sure would be to ask your smith who chambered your barrel.

I think my reload once I get some rounds down this barrel is going to be lake city brass, varget and 85gr barnes match burners.
