Ok so i have been looking at a B&C medalist to go on my sav. 10fp but first i have a couple of questions

am i better off glass bedding or pillar bedding? (my smith suggested pillar)

how difficult would it be for me to make it at det. mag.? i know kits exist for a r700 but what about the short action savage?

as always thanks in advance for the words of wisdom

*Edit where do i measure to get the 4.40in that i am supposed to measure*
