Thanks for the article.
I have 2 custom rifles
based on the 338 Norma Mag.
Found out about the cartridge last July. I thought the 338 was a propriotory cartridge, so I necked it down to a 30cal, and improved the shoulder angle. My gunsmith ( SSG/ Nathan Dagley ) got the reamer back in Sept 08 and built me a rifle. I call it a 300 JAZZ
, and it is an extremely accurate rifle. Shot a 2 1/2 " group yesterday morning with it at 723 yards, with only 1" in verticle. I am shooting 240gr SMK @ 2840fps with no pressure signs.
After talking with Mr. Sloan and gaining permission to buy his reamer, I had SSG make me a 338 Norma Mag as well. I received my 338 Norma Mag from SSG/Nathan Dagley last week. I have not shot it yet, but expect it to be just as accurate as my 300 JAZZ.
What I like about these cartridges is that I can shoot the long VLD bullets in the 30cal, or the 300gr SMK in the 338 and use the standard magbox, and not have to seat the bullets deeper in the case. Jimmy Sloan's design for that is right on the money.
I also feel that because of the design of the case that the cartridge will be forgiving in load developement.
After pressure testing was done in my 300 JAZZ, my load developement went very easy. My first loads were shooting .75 MOA out to 725yards. Since then I have done alittle tuning and am now 1/2 MOA or less out to 750yards.
I think the more people find out about the 338 Norma and it's offspring, the more popular it will become.
