My factory Accumark (.300 wby) comes with a heavy contour stainless fluted Krieger barrel,
It does not have an actual Kreiger barrel,it has a barrel made by Criterion,which is a company owned by Kreiger.Weatherby used the Kreiger name in it's advertising in the hope that people would assume that their rifles used actual Kreiger barrels.

Krieger barrels and Criterion barrels share floor space and personnel, but the clear difference between the two processes is cut rifling versus button rifling. Krieger barrels use steel (raw blanks) that has been cryogenically treated and then re heat-treated, whereas Criterion barrel material is not cryogenically treated.

[align=left] Q: Why is there some confusion that we might do button rifling? [/align] [align=left] A: In 1999, we started another barrel company Criterion Barrels that manufactures button rifled barrels for the O.E.M. market. These barrels are not directly for sale to the general public. Recently there have been some magazine articles written regarding this company which has caused some confusion. Be assured that when you order a Krieger Barrel, you are getting a single-point cut-rifled Krieger Barrel. [/align]
