You have to have a VLD seater so you dont damage the ogive, or modify your seater stem to accommodate it.
You also need to double-seat it for concentricity with an initial start on seating, then rotate the cartridge in the shell holder, and fully-seat.
I havent worked with it in many years, but have hundreds of them. I was using 30.7gr of CFE223 in Hornady brass. I dont think I ever saw super-tight groups, but dont really care since its something I would only use within ranges where 1.5 MOA is plenty accurate.
A 1.5 group at 100yds with that bullet means a cone of hit probability of 4.5 with a max radius from Point of Aim of 2.25 at 300yds, assuming you do everything else correctly.
1.5 MOA would be a 6 group or 3 radius from POA at 400yds.
