[QUOTE="Clark, post: 1278916, member: 6600"] If you go back 25 years when there were no www gun forums, just usenet on the internet, and when asked how you get that 3.25" 20 shot group 800 yards with a 308? The standard answer about bedding and pillars would be: You either touch at two points around the action screws, or you touch everywhere. Not much has changed. I am still not going to Camp Perry, but I am a touch at two points person. For the round bottom receivers, I custom build pillars with a slightly smaller radius than the receiver. When the pillars are prestressed [in compression for pillars, tension for re bar in concrete], they should easily open to the radius of the receiver so plenty of force is remains for the force multiplying effect of V blocks. The pillar is not necessary threaded, but just concentric rings in the outside to grab epoxy. The inside of the pillar hole in the stock is most easily scored with a tap. So that is threaded, but just to grab expoxy. [/QUOTE]
