Yes, the NOE mold. 1:7 twist barrel. I haven't done a lot of testing. So far the upper has only had 15 rounds fired.1680 is what I just picked up to try for subs.
CTS Tactical are you using the NOE mold? if you have any other details of your setup I'd love to hear it. I've got an 8" barrel to build up (1:5 twist). plan to only shoot subs thru it and have the NOE 247gr mold to try.
(looks like you posted details of the build while I was typing my reply- thanks!)
