I heard something about that but don't know any specifics. I do know there is something up, however, since Hodgon's site says there won't be any Retumbo available for this hunting season. What ever it was, it cost them a ton of sales....
BTW, I checked my notes and I got 116.3 grains of water with a once-fired, non-resized 300 RUM case filled to the mouth. For the sake of comparison, I got 92.5 in a 300 Win Mag case (that was WW brass, however).
And dammit, now that I know about it, I can't stand the suspense! I want to play with this new Nosler now!
