Okay about two weeks ago I posted on here about the 264 as a LR round. Since then I've settled on the 7mm Rum due to the fact of down range punch. As stated with the 264 barrel wear is a non issue as I have a barrel maker about thirty minutes from me(Gaillard Barrels). Now my set up is a M700 Sendero SF II with Leupold Mark 4 rings and bases with a Leupold Mark 4 6.5-20x50 Mil-Dot. Here is my question. What are very good dies to purchase? I've reloaded for many years and have tried LEE, RCBS and Hornady. I am after absolute precision here so what should I look for/what steps for I use?
