Had a guy bring this 25-05 small barrel action, wanted me to Thread it. had to put 1/2 28 on it and that just would work. Then made a T/P for it worked out good. Put a T/P for a ar beside it for comparison.
Townsend Whelan (of 35 Whelan fame) actually did experiments at his military armory on what barrel thickness was needed for structural integrity. With the rifles he was working with (30-06 caliber) he concluded that 1/16" thickness was enough for reliability and use. One of those useful tests that comes up now and then.
