I just picked up a rifle chambered in .338 Diablo, also called the .338 Edge. The round is basically a .300 RUM necked up to .338 caliber and has slightly more case capacity than the .338 RUM.

Anyone have experience with this round? For reloading dies, should I use .338 RUM dies and just back them off a bit. Or, should I purchase .300 RUM dies and have them opened up for .338 caliber and change out the expander ball?

I've heard that RL-25 and 225gr bullets are a good combo. Any other suggestions?

I really didn't need the rifle, but it was such a good deal, I couldn't pass it up.
For those interested, here are the rifle specs:
Rem 700 SS action (blueprinted)
Shilen select match grade SS barrel, #4 contour, fluted, finished at @ 26"
Jewel trigger
McMillan stock
Muzzle brake
