Dies & Taps?

[4ked Horn]

OK thats what I thought. Same as normal idea just a ton of accuracy concerns.

I was concerned that it had something to do with leaving the lathe lead screw engaged and cutting backwards with an upside down tool or something odd like that.

What kind of fit is there between the bbl and the action. Some have said it is a very close fit while others say the fit isn't critical as long as the shoulder and receiver face are parallel and the bbl is torqued to around 200 ft/lbs. Or is it both or neither?
