Re: 7mm rum and 168 berger vld
What rifle do you have? Usually, if you load to fit the mag, they wont come very close to the lands, depnding on what rifle you have, especially with narrow ogive bullets, like the Bergers. They might work fine loaded to fit the mag, but if you ask the guys in here and the Berger guys, I believe thay will tell you that Bergers usually work best seated to the lands.
In my rifles, Ruger M77 7mmRM, S&W M1500 7mmRM, Sako 85 Finnlight 300 WSM and Rem Sendero 300 RUM, you can not seat them to the lands and fit them in the mag, You can however, hold one down in the mag because the the nose on the top one is above the mag box.
