I have a new custom barrel for a Precision Target Action, but am puzzled on barrel vises. My barrel is a bull barrel with a straight taper. Barrel vises I have seen (i.e., Viper), seem to have the same radius in the two gripping halves, so how is that going to work on a TAPERED barrel? Maybe it can't, and I need to hold the action in some fixture vs holding the barrel?

Secondly, my custom ground recoil lug has no locating pin. How am I correctly locate and hold the lug without a locating pin? Apparently, some guns do not have a locating pin or recess for it, so short of buying a tool of some sort to hold the recoil lug in place while tightening the barrel, how can a "no-pin) recoil lug be located time after time (if changing barrels)?

Thank you.
