I'm going to start reloading for my 308. The particular load I'm going to develop will be for 1k target shooting with the 175grain SMK. Given that part of long range accuracy is a small standard deviation in velocities, I'm hoping you will chime in with powders they have used for the 308 that have regularly produced a small standard deviation. Further, I'm hoping you will share with me the type of primer and range of powder charge you have used to achieve a small standard deviation. Thank you for your help.
