I've been reloading for many years but just used the col printed in reloading manuals. I was getting MOA +/- .5 accuracy in my 308, 223, 22-250, 6.5 Creedmoor, and 220 Swift after working up loads.
I recently purchased a Hornady OAL gauge and bullet comparator. I was amazed at the difference in accuracy and the length I was moving the bullet out.
I'm getting .5-.8 MOA now in all these rifles using the same loads as before. I started at .020 from the lands but had to move it to between .030 and .045 in order to fit in the magazine. Even at that, the Creedmoor for example was more than .18 inches longer. All cartridges ended up being the maximum length that would fit in the magazines.
I wish I had done this years ago. I've got quite a few rounds to disassemble now!
