Well, i'm putting together a rifle. It'll be a Mclelland (I've given up trying to get his name correct) barrel (Any suggestions on a good contour? Outside of the same one used for most rifles, I don't know the ups or downs of other contours), on an H&S Percision Stock (Pro Tactical) with a Remington 700 BDL action, probably a used one from a gunshow. But, problem is, I am uncertain which caliber to choose. Obviously the 6.5/284 is the winner in this field, but, i'd like the experience of the recoil on the .300 Win Mag, in addition to the fact that it'll be seeing some military use, unlike the 6.5/284. Both rounds will burn through the barrel at about the same rate, so in the end, it's just which one to choose. I see people saying that the 142 grain is the best 6.5/284 round, but i'm not too sure as to what round would be optimal for the .300 Win Mag. Any suggestions/tips/pokes at my inexperience?
