When the bullet is, close, touching, or into the lands it is met with immediate Resistance when it is fired, which builds pressure, if you seat the bullets shorter you allow the bullet to get a "Running start" which dissipates pressure, what you are essentially doing is increasing the freebore, in technical terms it is called the "free travel clearence jump" or in layman terms jumping the lands, Weatherbys are set up with extra freebore, that is why they can sustain so much pressure 70,000 psi plus and get the speeds that they get.Originally Posted by FW Conch

PS: I never have any issue backing up or elaborating on any of my posts, if I did I would find another place to hang out, so fire away.

RUMs are like woman in Stiletto heals, you know they are going to put you in the poor house, but that has never stopped anyone from pursuing them.
scope-eye is absolutely correct with his answer - it can't be explained any better than that.
Is the ammunition to spec, and not someone's reloads?
If the FGMM is crimped as is sounds that it is, I would pull down the rounds using a collet puller, resize the necks to remove the crimp, and re-assemble the rounds with the bullet seated deeper in the case.
If this is a constant problem with your rifle, it may be worthwhile to slightly increase the freebore of your rifle, after consulting with a couple different qualified gunsmiths, of course.
