The Norma is more efficient because it's shorter and fatter than the Lapua. Think of it like a 7mm SAUM compared to a 7mm Rem Mag. My 7SAUM will match my 7RM but use less powder and easily fit into a short action.

Actually it is basically the 338 Lapua shortened and the taper taken out so you gain very little by improving the Norma compared to the Lapua. The specs I have actually show the 338 Lapua to be .002 larger in diameter at the web than the 338 Norma. Norma also increased the rated pressure for the 338 Norma but I would be very surprised if the Norma brass will handle any more pressure than the Lapua Brass.

You are right, both are based on the 416 Rigby case. I have been looking at so many different cartridges I was thinking of the 338 Extreme, which is based on the 505 Gibbs.

James,
The 338 Norma brass is every bit as good as the Lapua. Have 15 reloads on my 300 JAZZ (30-338 Norma AI ) brass and have annealled after every round.
Primer pockets are still tight.

What kind of performance are you getting out of the 300JAZZ?

210gr Berger's @ 3150 fps w/28" barrel
SSG built the rifle. The COAL is 3.50 with the 210gr Bergers @ the neck/shoulder and fits in a standard magbox. With 15 reloads on the brass, I am sure it could be pushed harder, but when it will shoot 2 1/2 " groups at 750 yards, I think I will stick with where it is at.

I wouldn't be looking to change your load either. I'm looking at another build in some variation of the 338 Norma. Now I have to choose between the 284, 300, and 338. It's a good thing that I have about a year to decide. Any more info or pics you care to share feel free!
