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?

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’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.
