Solitary, I am with ya. I have a load for my 300RUM with the 180gr TSX that gets .75MOA groups. I have this with the intention of Moose next year. But I read alot of those reports too and saw the pictures. Guess I will have to take out both those shoulders on moose

. Seriously those reports I saw where where with 270s and 06's and 308's. I have to think the velocity of a Wthby or RUM would have to help them mushroom alot more. But I am little concerned. This load I worked up with the TSX was supposed to be my last load made for this 300RUM. Before I burned out hte barrel of this one like I did the old one.
So I worked up a H1000 load for 200gr accubonds. This will my load of choice next year. Probably won't make a difference, but I would rather the bullet overmushroomed then under.
