I built one years ago because I had a 7RM with a shot out barrel, a Shilen blank for basically free, a reamer and lathe, and no money.
I sourced dies used for less than $30 and have never used properly headstamped brass, I run 7RM brass I get for free through the sizer.
I only use 7828 and 130s, monos mostly but I’ve used Partitions and Sciroccos some too. It’s a killing machine and I’ve racked up a good string of bulls and bucks with it. Being in a light easy to carry rifle helps make it a favorite.
