Iclimb,

What is the barrel length on that beauteous .400 Whelen ?

I use LEE and CH4D base-pusher, bullet-sizing dies, collected over the years.
I have not been able to find any of the N.O.E. sizers that I need, so have not tried them.

LEE are less expensive than CH4D, if you can find them.
Used to be able to custom order those.
Same for the CH4D.
I got some ready-made off the shelf by internet order, some by telephone call to ask/custom order, etc.
The same dies are useful for sizing lead bullets too, as well as applying the gas checks.
Soft lead sizes true.
Hard lead alloys might spring back .001".
Jacketed and Monometals of brass and copper might spring back .0015" to .002".
My hardcast ".458-caliber" bullets pushed through a .460" sizer will end up at .461" diameter,
whether using a LEE or CH4D bullet sizer.

Here are my CH4D dies for going from .416- to .411- to .408-caliber:
.412
.410
.409
.408
.407
.406

Just to show that I like LEE dies too, for going from .408- to .395-caliber (pet wildcat),
I use these LEE dies:
.405
.400
.397
.396
.395
.394
