Guys I am having a .338-06 barrel put on one of my rifles.  My question is: 

Is it easier to resize .35 Whelen brass or .30-06 brass to make .338-06?  I have pleanty of both.  My initial thought is .35 Whelen because .358 is closer to .338 to start with.  But in down sizing the brass the extra brass has to go somewhere.  Will I have to turn the outside necks and/or ream the insides?  As for .30-06 will that be a 2-stage resize or can it be done in one sizing?  Would appreciate some input. 

I haven't posted on here much but have been doing a good bit of reading.  Seems like a lot of experienced reloaders on here.  I've only been doing 8 yrs and I learn new stuff all the time.
 
Thanks.

You could just buy some .338-06 brass and not have to deal with it.  It is expensive, but it seems it would be worth the money to me.

Generally you'll get straighter necks by sizing down rather than up. But that's only for the first sizing; after firing them once it doesn't matter. There isn't enough difference in .338-06 and .35 Whelen neck diameter to need to turn or ream necks afterward. If you decide to neck up .30-06 brass instead, it can be done in one pass.

I  agree with Mr. Barsness, necking down is preferable to stretching an already thin neck to make it even thinner.  Necking down a step or two rarely makes necks as thick as many seem to think.

Thanks guys,
 
A question I forgot.  If I use .35 Whelen brass will I need to trim it after sizing?  Will the sizing make it longer.

All I can suggest is do it and see.

Well my dies arrived and I resized about 20 cases just to check.  Most cases did require a good amount of trimming.  Some cases barely needed it but some needed a lot so it averaged out. 
 
I knew that the brass had to go somewhere.

Safety factor in using 35 Whelen brass is good too. Should some idiot put a 338 in a Whelen at least it won't blow up the gun. Were it headstamped 06' and he put it in an 06', it could be very bad.
