Home Forums Hunting & Shooting Express Rifles and Big Bores Only Question for the .400 Whelen Crowd

There are a couple of articles on the .400 Brown Whelen from 1991 and 2006 publications.
The author of the latter basically followed what the former author did.
Their load data are the weak sisters to what the .400 Whelen-Petrov does with aplomb.
The whole purpose of the .400 Brown Whelen seems to have been fear caused by
improperly chambered and loaded "supposed .400 Whelen rifles" of the past.
After Michael Petrov the .400 Brown Whelen has become more obscure.
Best thing about those two articles is how well they illustrate the "reversed XTP" fiire-forming method,
which is how I do it.
Why heck, I might have learned how to do it from them.













If one were fearful of the .400 Whelen headspacing, one could make the reamer shoulder diameter 0.461" minimum instead of 0.458".
One could also get rid of the neck taper in the .400 Whelen-Petrov chamber,
make a zero-taper neck with same Neck-1 and Neck-2 diameter minimums in the chamber..
I have a feeling that is what the .400 Brown Whelen did, but I have never seen a reamer drawing for it.
The .400 Whelen-Petrov is little different, but it is less prone to failure in combat feed mode,
in untidy environments and impolite situations.
