[QUOTE="Trickymissfit, post: 641075, member: 25383"] Note: I also said with heavy bullets. When using the small stuff the other is better (.300 Win). But when you move into the 200+ grain bullets the Norma mag shows up in force. I also consider the Sierra manual to be good bird cage liner most of the time. The neck is about .14" (figuring on a 2.56 case in the Hogdon sketch) longer with the Norma, and that alone makes for a better design with 200 grain bullets. With 165 grain bullets there will be no differnce between them. Add to this the known fact that longer necks usually produce longer barrel life. I see where your comming from with the free bore issue, but also beg to differ with you when you load a 220 grain bullet in the chamber. There are still a small few that are using the .308 Norma in 1000 yard benchrest shooting, but have not seen a 30-.338 listed in a very long time. To be exact there are less and less .300 Win mags every year as well. With a 220 grain bullet .218" of freebore means very little, but can see the issue with 165 grain bullets. Actually that free bore (as long as it's not excessive) will alow you to seat the bullet well out of the shoulder, and a good long at the long range section in the AA manual shows this. The 200 grain bullet in the 30-.338 (or Norma) goes at about 2900fps, but the same bullet in the .300 mag goes goes the same speed with seven grains more powder in the Hogdon manual (most manuals show it much slower) Interesting conversation, but i'm staying with the Norma mag. gary [/QUOTE]
