I've had a few too. I don't know anyone who has a dead set formula for "this is how you bed an "H" barrel SMLE to optimize accuracy". There is still a solid crowd who shoot them every week, and these guys ALL have one they got that shoots well, or through trial and error they worked up. Many of these "worked up" winners, use glass, or body filler as bedding compound at various points. For the sake of keeping my builds as "original" as possible, and to build my skill, I'm not using anything other than traditional methods, stuff how long it takes. These old school guys did it once upon a time, time and time again, and I'll be doing it, hopefully as well as them in the not too distant future... that's the plan anyway.
