Thread: 284 win slow speeds

@Jim356

.317 neck on the reamer i see, was that the gunworks reamer?

You say a loaded round measues .314 neck dia, what is the dia if you move the calipers down closer to the neck shoulder junction? 284 is pretty fussy on neck clearance, and while it appears you have 3 thou total neck clearance, thats the bare minimum i reckon, and im picking down towards the shoulder you may not have that much.
