Understanding a little more about case prep which I understand, that was the crux of the article. However I read different things about run out, or being slightly off of, on, or slightly into the lands. The lands I assume in the start of the rifled portion of the barrel. How do you know that your bullet is touching the lands or not, where does this measurement come from and how is it obtained?
While this was an informative read to me, and I may be asking these questions in the wrong place, where might I find more information on precision reloading and that is hopefully simplified eough for a beginner to understand. I have a habit that when I decide that I am going to do something I tend to jump in head first. I recently received my NF glass for my build. Now all that I have to do is decide on a cal.
Buy a Hornady Lock-N-Load O.A.L. Gauge, you won't regret it. This is by far the most accurate way to measure how far your bullet is from the rifling. If you really want to get serious about consistent measurements, get the Hornady Bullet Comparator also. Good luck.
My 22-250 Savage 12LRPV likes a .0255" jump to the lands with 52gr Speer HPs, and my .308 700 VTR likes a 0.076" jump with 178gr A-MAXs. Haven't fiddled enough with my other guns yet, I just bought the O.A.L. Gauge about 2 months ago, along with the Comparator. Couldn't be more pleased.
