Yote,
A friend of mine and myself were working on a 260AI project through the Encore system. We each had custom barrels made and most of the Encore tricks recommended by Bellm. This friend asked him how tight should we have the hinge pins 1X, 2X, etc. The recommendation was that we grease metal to metal contact and use a rubber hammer to "wack" them in.
Mike Bellm has forgotten more about Encores than I'll ever know, but I did not like that idea. I asked our barrel maker and that is when he said the pins are harder than the frame and that I could damage the frame if I "beat" them in like that.
On this barrel I do use the 1x pin and have to tap in the pin, but I'm to for "whacking" the pin in. No I have never used the reamer. I didn't want to start that. Once you ream your frame you would have to ream every barrel lug after that. Hope this answers your question.
