It depends on the kind of stock your rifle wears, and the type of rifle. Some designs, like the Weatherby MK V and Mausers aren't really suitable for pillar bedding since the front pillar would end up so short. Most others can be pillared. As for stocks, pillars really help wood, aren't a bad idea for Mcmillans, and are absolutely required in foam stocks like Bell and Carlson (excepting the Medalist series). The medalists, HS Precision, and maybe others have the aluminum bedding blocks. They don't need pillars. Rimrock stocks have fiberglass G10 pillars already built into them. So, I guess what I'm saying is what rifle do you have? That will determine how you bed it.
