Hey Lynn....I'm using Reloader 25 over Fed210M primers. 210 Berger VLD's about .005 off the lands, pointed with a Whidden die. They go out about 3,120 fps at 2,500 ft elevation from my 34" Oby.
I really enjoyed the Nationals last weekend and have decided to build a 6mm just in case I ever run into those great conditions again. I may try to make the 600yd Nationals next year if I get the new gun working in time.
