[QUOTE="ShadowAviator, post: 3047950, member: 124813"] MidwayUSA has reloder 10x last time I looked. 1200R is discontinued, I think. With 10x and 270gr speers. I am not quite getting the velocities in the data you just posted. This could be due to me having a new barrel. I have heard a barrel can "speed up", after 100rds or so. I will be trying magnum primers soon. Regarding the case length and short neck, this is from the FAQ. "Question – Why was the 375 RAPTOR neck shortened and not just left full length after resizing? Answer – The 375 RAPTOR was designed to be able to shoot magazine length the full range of .375 caliber bullets including the Sierra 350-Grain Match King which has a .720 BC below 1700 fps. Why does that matter? If you shoot subsonic, the 350-Grain Match King has 60% more energy at 100 yards when fired subsonic than the 300 AAC BLACKOUT shooting a heavy OTM bullet subsonic. In addition, the 375 RAPTOR gives options like the Barnes 350-Grain TSX or Lehigh 295-Grain Controlled Fracture." To ease the shortening of the brass, I have seen some use a small chop saw to cut most of the case neck off, then trim the rest. What monolithic are you thinking of using? [/QUOTE]
