If that is made on the same brass that they sell, then, that should be fine.

jackie,

Blue or Brown box? I know I have Blue box, not so sure about Brown. I can send a few pieces if you wish. Lots of IMI is available, and is similar. RSVP via PM please.

HTH,

Neck dia. on a loaded round was .3366" , so less .310 bullet dia. gives .0266 or a neck thickness of .0133. Just at the front of the web was .411". Will have to measure the web dia. farther down and get that for you.

That’s what I am looking for. A .332 should be perfect for a tight neck for just a light cleanup.

Blue box, since that is what is available now.

for this project, it has to be Lapua.
