I just finished reading the article "Switching Barrels in the Field" pg 51, PS, March, 2009, and was a bit surprised to read the various claims/statements by the articles author. Either he is leading some readers down the wrong path or some of us on this messageboard are all wet.
Maybe I am just plain ignorant in the way I gunsmith my accuracy rifles, but here are the various statements that caught my attention, and are contradicted to my own gunsmithing practices and to most of the gunsmithing practices that I read about on this messageboard for a Remington model 700 rifle;
-"The barrels can be fit so that they can be hand-tightened" only.
(without the need for a barrel vise and wrench)
-" I.....checked the action for 'trueness' by inserting and indexing rod through the receiver and measuring the run-out as I hand-turned the lathe."
(less than .002" runnout was considered acceptable without mentioning where and how the measurement was made. No mention of action lugs, action face or action thread runnout was included)
-Using a chambering flush system " the chamber is so smooth that a 800-grit paper is used to rough up the chamber a bit so the case can grip the chamber walls better."
-" I put a 60 degree chamfer on the chamber so a cartridge will feed better."
Well, the author of this article was all smiles and peachy happy with the final product written about in this article, so who am I to rain on his parade.
Perhaps something got lost in the translation between the author/gun owner of the article and the actual gunsmith doing the work.
Who here on this messageboard does there gunsmithing work using these same methods?.....................Don
