I need help spec’ing a reamer for a 20SCC . Been thinking about a vartarg when I found what limited info there is on this one. I like the 40 degree shoulders and wanting no turn for Lapua brass. No idea about freebore, I am thinking minimal to none for 32-40 grain bullets. Found a LV 11T Krieger planning on putting on a bat SV if I can find a .223 bolt for it. Any info is appreciated.
