Making 300 RUM cases out of Norma 404 Jeffery cases?

[Kanab]

I want some higher quality cases for my 300 RUM and a 338 RUM I am having built. Are the Norma 404 Jeffery cases a possible source to form some out of? Is the case wall thickness at the web of the Norma brass at least equal to the Remington RUM cases?

The head diameter of the Jeffery case is too large for the RUM Bolt face.

I was going off the statement that the RUM is based on the 404 case.... I guess it isn't?

What about purchasing 2,000 once fired cases and sorting them by weight/run out?
not .338 case is .1" shorter due to neck being blown out of 300 Brass (to form the .338) (at least that's what remington tech support told me).

The RUM cases are based on the 404 case, but with a rebated rim so they will fit in the smaller american actions.
The 338RUM fits well in the Rem 700 for instance, but the 338 Lapua requires opening the boltface up.
Where does a guy go about buying 2000 pieces of once fired RUM cases?

Remington's web site says that the 338 RUM was shortened so that the full range of .338 bullets could be used in the confines of the Rem 700 Action.

Hello My first poast have stumbled upon this site. There are other people like me . I have always enjoyed shooting far away, with every thing that shoots accutarely. On the weekend I was at the gun show in Calgary and picked my First 300 rum in a light weight Christensen's Arms beautyful accurate carry around long range D.R.T. rifle it also had a 5-22 night force scope on it . I never did like Rem brass so started looking for brass and federal 300 rum brass at ph# 1-307-686-4008
I would like to get 250 rds to canada but it looks like i am going to have a hare time getting it here.
