Why the 338 edge

[bohunter7]

Just wondering why folks go with 338 edge over other 338's like Laupa or even the 300 RUM? I understand u must "neck up" a 300 RUM case. Is that difficult to do?

"Necking Up" the brass is not hard at all. I have only been reloading for less than a year and the process is pretty simple. When using 300/375 ultra brass to make your edge brass requires a hefty use of sizing oil that first sizing. I have a 300 ultra so I had a ton of brass to get me started. You can either buy edge dies or go the economical route and get some 338 rum dies and a 375 rum full length sizer. Set up your 338 rum die to only size the neck, barely kissing the shoulder, and take your new, neck sized brass and run thru the 375 GUTTED full length sizer die. I had to wait on the 375 dies, so the brass I have been running has only been neck-sized in a 338 rum die. Guys on here say you can get a few reloads before a Full length sizing is necessary

I'd say that if you get a shoulder bump from your 338 RUM die you should be able get the maximum life from your case without ever having to full length size it.

My next build will be a 338 Edge. Donor action is a Weatherby Mark V.

Why Edge vs RUM. Performance expectations. For 338 RUM, Remington shortened the case to prevent miss chambering or some other nonsense. The Edge retains full 300 RUM capacity so the Edge is 'faster'.

Why not 338LM. No bolt modifications required. Not as 'overbore' as 300RUM or 338LM and my gunsmith prefers it that way.

Have not chosen the barrel yet. Douglas, Hart, Lilja, Shilen or Pac-Nor. I have 3 Pac-Nor 3L barrels now. Very, very happy with them so ++ for Pac-Nor.

Actually, there is an im portant bolt modification necessary to go to the Lapua from a RUM. The bolt face of the Lapua is larger than the standard magnum bolt face and it will need to be opened up to around a .600 diameter.

You miss read my post. I'm going with 338 Edge because no bolt modifications.

I know the LM requires it.
