Now, after saying that, I am a very disappointed 7mm RUM owner. When I purchased my model 700 7mm RUM, you could get 140, 160 and 175 gn loads from the factory. Now the only factory load for the 7 RUM from any company is a 140 gn CLU. I can't believe a cartridge as powerful as the 7 RUM and you can only get 140 CLUs. I'm ready to sell my rifle, and move to one of the WSMs.
Sounds like a textbook case for getting started in handloading
