300RUM with 240gn SMK is mine but I sure hope it dosn't come to that. Hopefully the edge will be safer as its not a military round. It seems they are mainly after 338 Lapua, 375 and 408 cheytac, 416 barret and 50 cal tacticool rifles.
I was thinking the same, not much left when you take the big .338's out of the equation. That is why I was thinking of setting the barrel back to .338WM.
Better still, just get the barrel re-stamped as a .300 RUM and continue to shoot it as a .338 Edge. The flat foots would never know the difference unless they mic the projectile!
