ThanksI was looking into this recently and it sounded like the 0.150" freebore was desirable. The SAAMI freebore is 0.199".
Thank youI sent a 140 Berger to JGS seated just barely above the neck shoulder junction and they came back at .160.

I guess you could say that.So they were touching the lands at .160?
Just trying to figure out your post. Wasn’t sure if it was touching the lands at the .160 freebore or if that was the freebore you went with to be a certain amount off the lands.I guess you could say that.
I just sent the dummy round to JGS, my guess that was to the lands.Just trying to figure out your post. Wasn’t sure if it was touching the lands at the .160 freebore or if that was the freebore you went with to be a certain amount off the lands.
This is correct, if the bottom of the print doesn't note a "jump" (and you didn't ask for one) it'll be set up to touch the lands with no jump.I just sent the dummy round to JGS, my guess that was to the lands.
