Hi i just purchased a chronograph so i can start fine tunning my reloads for my 338 lapua. I have done some research but did not come up with what i was looking for? so i guess my simple question is how do i use my chronograph the callculate pressures. is there a a formula i can use? also i have a 26in barrle 28 with a brake? dose the brake make a differnce? i have been only reloading for a year, so i have alot to learn. i have been making my reloads relativly safe. I do have one good load that i shoot out to 700 with h1000 and 300 gr otm at .10 off the lands. But want to know my 'sd' and 'es'. and most of all what pressure im at right now.
