It has less to do with more meat around the chamber (although the increased hoop strength doesn't hurt) and more to do with the ability to fit larger bolt lugs. The tenon diameter limits the size of the bolt lugs. Most companies that build a .590 Lapua bolt face action also increase the bolt...

To clarify, this will be a super heavy bench only rifle, yes? I shoot both 338 Lapua Improved and 338 Norma Improved quite a bit. If you are going the Lapua Improved route, you are clearly chasing maximum performance. In my opinion, I would consider a beefier action with 1-1/8 tenon threads...

LE Wilson chamfer and deburring tool is what you seek.

I am stuck in analysis paralysis and need some expert input on a new build. I want to build a lightweight (within reason) 338 Lapua AI for a dedicated elk hunting rig. I currently shoot this cartridge in a 25lb bench rig and am 100% set on the chambering. Probably shoot a combo of 300...

Pretty sure those are x47 cases. But your point is still valid. I'm done. Carry on. Learning a lot in this thread.

I'm still shooting 7 Rem Mag, and don't anticipate switching any time soon. Slightly more case capacity, really good ADG brass, and tons of factory ammo. The kids can have the PRC.

SAC build on a Fuzion action. She prefers 185 Jugs.

What kind of improvement are you looking for? 338 Norma has ~10-15 grains less case capacity than the Lapua, so all else being equal it is a little slower than the Lapua (improving the Norma closes this gap). The Norma is a shorter case, which allows you to seat long bullets out of the powder...

Correct, 338 Norma improved is a wildcat that sharpens the shoulder angle while pushing the shoulder forward, and also removes some body taper. Similar to other Ackley improved designs. These improvements increase case capacity and lead to more stable case dimensions, at the expense of...

Barrel life is a major factor with 300 Norma in my experience, to the extent that chasing maximum ballistics wasn't worth it for me. My first barrel lasted around 600 rounds. I also couldn't get the super heavy Bergers to shoot as consistently as the 215 grain, so I mostly shot the 215. As an...

Just curious - why would someone choose this chamber over a 28 Nosler, which is commercially available and has outstanding brass readily available?

300s at 3120 out of a Norma improved? There is no way that is safe. That is XC territory.

Why would you do a 30-338 Norma improved when you could just do a 300 Norma improved?

Nice setup, looks kind of like mine. How do you manage the annealing time?
