I loaded some a couple weeks ago, but don't remember the specs...I'll look them up when I get home tonight.
OAL for me was set to magazine length since I use my 7Mag as a hunting rifle, I want it to be a repeater, and not a single-shot.
Your OAL will be different. The sweetspot in every single rifle is different. The VLD's seem to prefer to be as close to, or touching the lands as possible, from my experiences with them. My .308 likes them touching the lands, and so does my 7mmSTW, which are not rifles I hunt with. They really only see bench-duty most of their lives. Occasionally I have taken the STW hunting and been successful....A little too successful on close-range whitetails....It can be quite brutal and devastating on meat-loss with 160gr bullets or larger.
I am trying to save to have my 7Mag rebarreled (heavier contour & 1:9 vs factory sporter barrel & 1:9.5 twist) and buy a different stock for it, but right now I can see it will be quite a while before that can happen, so I'm just gonna keep shooting out the factory barrel for now.
