its my mates although he bought the gun for the rifle itself a few years ago, 20 inch barrel, felt good and didn't look into the 338 rcm too well but wanted the 'magnum' and thought its the equiv to a 338 wsm.. which it-is-to -a-degree.. and that's until Factory ammo A- availability comes into play and B- the price of said ammo, if you can find it close by (cant be freighted)..
he does have dies altho only 50 cases, but isn't 'set up' to load and doesn't sound too keen on it yet..
So around the fire at sambar camps we have been talkin about what to do with it, finding a buyer is almost just a waiting game which could go on and on, trading would get SFA for it.. so I thought about a Rebarrel job..
He's other option, he is a Howa fan and so the 375 Ruger in 20 inch appeals to him, and also to some degree the 45-70 marlin lever scoped.
I was thinking along the lines of, 300 RSAUM , 300 WSM , 325 WSM , or trying to talk him into a 270 WSM !
he wants to be able to buy Factory ammo for a while (doesn't shoot much, but now understands importance of saving brass)
ive done research and found the rim dia for RCM n RSAUM is .532 & .534, which I think is the only part that matters, case length is the Same also. however the Base diameters are, .532 & .550 .... but I think that's to do with the Chamebr , not the Bolt face..
this way a Custom 18-19-20 inch tube and hes pretty happy. and is lookin at around $600 for complete fit ready to shoot with a blued steel tube basic standard etc.
