I consider the length and weight of barrel deciding whether or not to bed in front of the lug. A short light pencil profile barrel probably won't need or benefit from the extra support as much as a full Bull @ 30 inches.
As far as doing full or partial bedding with or w/o pillars on a Rem. or clone action build, depends on the stock type and the intended use of the build.
Generally speaking, I do full length bed, some times with either alum. pillars, some times poured epoxy, even lamp ferrules. If the stock has alum. V-block I still skim bed them for fit and bed the recoil lug.
Aside from chassis stocks I think pretty much all will benefit from either or both.
I did a lot of research on epoxy bedding before nervously attempting my first years ago, most if not all of the top custom rifle builders across the different shooting disciplines full length bed with pillars, I just figured there must be a reason.
