As I continue to explore my options for having a rifle re-barreled, I have noticed a .338 Brown Whelen as a chambering option with some barrel manufacturers. Exactly what is this? What case is it based on? And how involved will case forming be? What would the difference be between the .338 Brown Whelen and a .338-06 AI? Thanks.

The "real" Brown Whelen is another improved version of the '06 case necked up to .358. Seems to me it had a more moderate shoulder angle than the Ackley. A 338 version would just have a differnt size pilot on the reamer.

<br>The Brown-Whelen cases are based on a 30-06 with the shoulder moved forward creating a shorter neck. I think they are also "Improved". You would have to neck 06 cases up past .338, then back down in the Brown-Whelen dies to creat a shoulder for headspacing. Then you will have to fire form the brass to the new chamber. Too much scewing around for me.

Take a look at my .350 Howell. At http://www.hunting-rifles.com you'll find its ballistics, case drawings, and comparisons as well as brass, dies, ammo, and even complete rifles. It takes the .35 Brown-Whelen a logical step further, with factory-made brass to boot. No screwing around.
