Hi all I have a 338 SC Edge that I built on an extremely low budget and this is how; 1st I bought a 300RUM Remington for about $600 then killed a few whitetails with some 180gr smk's one pretty close, the other only 300 yard with no elevation adjustment which was nice, so then I orderd a barrel from ER SHAW in 338 rum and had them thread the end for a Badger FTE break which I opened up with a size T drill bit and allso bought a badger recoil lug and sent it to ER Shaw so it would all fit wright, used a 338 Edge PTG reamer and a hand crank from my Lexus LX450 jack (but you can use the PTG extension) and reamed it out with a bunch of cutting oil to the proper head space using a PTG 300RUM head space gauge (easy) So then I bought a HS Precision stock and took a dremel to the back end of the action to make way for the Wyatt box for the added OAL. Ok it was a lot of work but this thing drills holes one inside the other @ 100yds and @ 400 I get 2 inch groupings. So here is what I am using : Nosler Custom 300 RUM brass, 96gr H870 don't ask I got a ton of it before they stopped making it, CCI Mag primers, and 300 SMK's @ about 2750fps. (Now time for the reality) I shot a whitetail at about 100 yards on an uphill slope and it not only blew up, but it went about 10 ft threw the air before it hit the ground; not exactly long rang hunting I know, so from now on if I use this gun it's going to need to be a lot further away if I expect to get any meet off it.
