I've heard about this but never actually understood it. i always worked up loads until my rifle shot a good group. But after reading a couple threads on it I started watching videos about it. And it makes a lot of sense. My previous shooting was always no more than 200 yards. Not far enough to really tell if I was getting optimum performance from my rifle/load. Now I am going to do this with 2 rifles. My model 70 in 270WSM and my soon to have Begara B-14 in 6.5CM. I plan on doing the 10 shot method in .2 or .3 gr increments and do it twice to verify my results. Hopefully I will get a plateau up around the top end velocities. Once that is done and find the sweet spot I'll start playing with seating depth to get the most out of my rifle. I will take any advice on this.
