i am going to take a few inches of an old 10/22 barrel
i have watched a video on youtube from MidwayUSA where they use lapping compound on a coach screw to crown the barrel (dont laugh ! lol)
as its an old barrel i dont want to spend loads getting it done professionally, as its only a wee gun for plinking with
so here is my questions......
1. where do i get lapping compound to do this ?
2. what type do i go for ? smooth, medium or coarse etc ?
3. is it possible to buy it in small amounts, as i only need a teaspoon amount ??
i know someone out there will be an expert at this
