[QUOTE="Trickymissfit, post: 452773, member: 25383"] I've made about a dozen of them thru the years, and the best I found was made from precision grade Thompson Rod (it comes in two or three grade levels). The stuff is harder than your exwife's breath in court! Comes with .100" case on it, and will usually be about 62RC, and is dead strait right out of the tube. Once you break thru the crust it machines very well. I used to use lapping compound (5a & 7a) till some folks up in Michigan turned me onto a powder that is called "non-charging lapping compound." Who makes it? I don't know, and it's just a yellow colored powder you mix with very light weight spindle oil. It will not imbed in the scope rings, so it won't attack the scope tube later on. I gotta find a new source for the stuff as I'm about out of it. gary [/QUOTE]
