I'll have to look for the Norma. Local shop only had the Federal and Winchester. Local Sportsman had Winchester, Federal, and Nosler with the Nosler being the fastest. Didn't buy any as this weekend is packed with work/horse/kid stuff, so no time for guns.
The Winchester for sure has a smaller rim diameter than a Norma, Sako, Prvi case because they are based on 30-06 cases. I'm not sure of the real world implications, just so you know.
