with now the very good availbility of 300 ULTRA case ( even if REM case are not RWS quality ) I think that for my own use I never built a new wilcat base on 404 case .
a wilcat in 338 cal base on 300 ULTRA can easy duplicate the 338/404 without need of :
alter the bolt face ( excpet for SAKO extractor wihch is a must a custom rifle
after to have square the bolt face and lugs )
costly reloading tool a Redding S die in 300 ULTRA open in 338 with a bushing in 338 work fine , body die can be made by the same way .
you can sort your cases because REM case are available by bulk quantity
you doesn't cry when your favorite hot load destroy case after only two reload , rather to burn 1.5$ r more in each 404 case without the count of forming work.
good shooting and enjoy easy way .
