I am getting ready to embark on developing a .308 target load for my Remingotn 700 LTR out took a max of 600 yards. I ahve never worked up a load extensivly before. I mostly been trying different bullets with medium charge weights and had some very good accuracy. My goal is to find the most accurate load i can for my rifle and load a lot about realoding. Not going to be shooting matches or defending the perimeter from zombies, this is for my own amusment and satisfaction (although i would like to get into matche shooting someday). I am looking for advice on how to go about developing a load, what order to change variables, etc. I just bought 100ct of Lapua brass that i will use throughout testing. Bullet will likely be 168gr or 175gr SMK. So variables to test that i can think of poder type, charge weight, primer, seating depth.
Where do start?
Do i just pick a recommeded powder and primer, starting load and work up untill accuracy peaks and then start slowly changing seating depth?
Not sure how to best go about this mehtodically
