Re: have to seat bullets below saami to chamber
My brother has a factory ruger in 300 h@h that is often under saami; depending on the bullet nose profile of course.
The long throat thing seems to be more of a remmy thing than anyone else. Most of my( non rem 700) pipes aren't that much over with the bullets seated close. I seat to fit my mags though, so it isn't of that much importance to me as long as she groups and she's safe.
Shoot her a few hundred rounds and she'll grow. If you can't stand it have a 'smith lengthen the throat a bit.
