What's your neck wall thickness or the loaded round dimension?

.316. A bit tight. Can't recall what bushing I'm using. Gunsmith cocked up first time around and used a .316 reamer despite my giving them a dummy round that measured the same.

Turned necks on mine at 14 thou’ at .312”. I’m using Redding Comp bushing neck die with .310 bushing to give 2 thou of neck tension. Typically gives single figure 5 shot ES. Interestingly, Lapua brass neck wall thickness varies by up to 1.5 thou’ on my Mitutoyo ball micrometer, which is good compared to most, but worth addressing nonetheless.
