7.62x39 "Spec II/Wylde"??
Is there an improved accuracy version of either the SAAMI or C.I.P. 7.62x39 chamber? Something with a more accuracy inducing throat design and a tighter chamber neck?
I've got a couple of AR upper and a CZ527 in 7.62x39. If a chamber more conducive to maximum accuracy exists, I'd like to have the CZ barrel set back and re-chambered.
So, has anyone designed such a chamber and if so, who has a reamer and can rework my barrel?
JGS makes reamers for "match" 7.62x39 chamber
I found out that JGS has a reamer design they call the "7.62x39 Lapua". It's their print # 3514. It has a cylindrical .3114" dia. X .078" long throat transitioning to a 1 degree leade. Very similar to the .223 Wylde design.
Now if I can just find someone making .310"-.311" barrels with this chamber design. Any suggestions on what barrel supplier might be using this?
