I have built a lot of these with a .293nk, unturned Lapua brass once loaded comes in at .290 +/- half a thou.
.060What freebore did you spec?
Thinking about building one to shoot the 147ELD, was going to order zero throat and a separate throating reamer but rather not. I wonder what the oal would look like with that bullet and .060 fb. I don't have any in hand yet.
