I've been reloading my .308 for about 1 year or almost (still a newbie). I read the manuals and know the safety precautions and even went a little further to figure out the best COL for my gun. I've got about a 5" drop from 200 - 300 yards and I've been told by several people at the range "that's not right check your velocity". I have a chrono but haven't had the opportunity to use it yet. I haven't seen the Hogdon manual yet, I'm using Hornady, but I've been told the max. charge for my load is greater in the Hogdon manual than the Hornady manual. (I'm using Varget and 150 gr SPBT Hornady bullets - sorry I don't have the manual in front of me at this time to give the readings) My question is... if there is a difference - Do I use the powder manufacturer's manual or the bullet manufactureer's manual? I know I have to check the bullets for signs of excessive pressures, and the Chrono will help, but which is correct or safer?
