[QUOTE="J E Custom, post: 507551, member: 2736"] I agree to a point because most materials have different coefficients of expansion so they may change dimensionally with temperature changes. "BUT" the pillars will return to there original dimension when the temperature returns to the same as when built and it is very very small. Where as the stock material once compressed will not return all the way back and continue to lose the original dimensions with continued compression by the action screws. The main benefit is to keep the bedding material from compressing. most bedding materials will have a coefficient of expansion 8 to 9 times that of stainless and left to its own (No Pillars) will eventually compress enough to loosen the fit on the receiver. Having bedded both ways, the pillar bedded action lasted much longer before skim bedding was nessary to improve the fit. As allways this is my opinion based on experience and with a little applied science. You may not be convinced, but I am and will continue to pillar bed all actions in search for more accuracy. Good shooting J E CUSTOM [/QUOTE]
