Randy,
I use a lot of 1/4 X 28 threaded nipples.. and was always told my brother in law, who is a mech Engineer.. it only takes three complete threads to create a full strength mechanical hold.
if you consider the information here http://www.gizmology.net/nutsbolts.htm
this page mentions anything over 6 threads is basically superfluous.. calculating that each full thread of a 1/4 X 28 is .o35714" approx...
6 X 0.035714 = .21484
So if your barrel has a .217 wall?
never hurts to go ahead and use a chambered breach.. they can be made in a home shop, as I described in a previous message..
but it never, ever, hurts to have it professionally made?
Respect Always
