Most of my internet time is spent at work, and the firewall blocks me from looking at most gun related sites, so I need you guys help. Could someone please explain to me the difference in glass bedding vs. pillar bedding. What are the pros and cons of each. What do you guys mostly do. I will be doing one of these to a Remington 700 22-250 and a Wincherster 70 Coyote 270WSM.
