Federal Brass for .338-06 Project

Since the Federal cases are heavier and especially thicker in the neck, thereby probably resulting in better bullet to neck tension after sizing and seating, would probably be the best choice. Winchester brass, although good with the mag calibers, seems to provide the least neck tension while remaining as '06, and would stay that way when necked up. Remingtons should fall in between.

Have dies coming in today for new 338-06 rifle. Have a lot of 30-06 brass in Federal, Rem and Win. Leaning toward the Federal brass for resizing to 338-06. Has any one used these components and what results did you have with them.
Yes I have, I would use all three, four or five. After firing I tumble, when sorting after tumbling there is nothing that makes more sense than using different head stamps when sorting brass. As you can see it is assumed case bodies are thicker and or thinner. I have 30/06 cases that have thin case heads and thick case bodies and I have 30/06 cases with thick case heads and thin case bodies.
Then there is a problem with reloaders that do not measure before and again after. If you neck the 30/06 case up to 338 the case will shorten at least .035”, same thing happens when necking the 30/06 case up to 35 Whelen. I have formed wildcat cases using 30/06 cases. During forming and firing the cases shortened .045”.
Point? I would suggest you anneal the 30/06 cases unless they are new/unfired. I have purchased 1,000s of pull down 30/06 cases from Pat’s reloading in Ohio and other places for the sole purpose for forming.
I started to build a 338/06 then changed my mind. I built a 338x280 Remington. The case body on the 280 Remington is longer than the 30/06 case body by .051”. I used 280 Remington cases. The 280 Remington case is .041” longer than the 30/06 case, when the case was necked up it shortened.
