Tenon Measurement to use for coned bolt action?Update***

[hoz53]

So where i would start on an unknown action you dont have a print for is measure its headspace, cut the tenon that long, screw the barrel on against the bolt and measure the gap inbetween the barrel shoulder and action, add .010 to that and cut that much off of it as measured with the pma woolums barrel chambering depth mic. Thats a foolproof way. On a remington style just measure to the top of the lug and top of bolt nose, take .010 off of those measurements and cut your counterbore and tenon length accordingly.

pretty detailed-- Ok right Ive been measuring the remington counterbore actions like that all along. the thing i got here is on a cone bolt use the measurement to bolt face. with a cone bolt obviously you have to cut the cone before you measure the gap right? so then when you cut some off you have to deepen the cone since you cut part off right? finding the tenon length to start was about not having to recut the cone for me. would not be difficult i know. --- i just went back and looked at those 2 pics to think about this again. i got same conclusion. the nose of the bolt on a coned bolt action goes into the barrel cone a little. so figuring how much to cut off the tenon by measuring gap you have to cut the cone first to get the measurement you want. thanks for all this info

Just giving you one way to measure it. This way is a couple more steps than the other method i told you about but both will get you closer than it needs to be
