    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.

    25 -06 maybe? Not much barrel wall thickness left on that muzzle, might need the TP for structural integrity. Lol

    If I ever decide to build a ship in a bottle, I'll call you to mfg the cannons!

    Interesting job, thanks for sharing it.

    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.

    "Reliability and Use" includes what degree of accuracy? How much shift of POI as it heats up? Proving a concept does not mean results are desirable. There are some fairly thin barrel liners but they always rely on an external "shell" of some type in the real world.

    Wild Rider,

    Sorry to be so slow to answer; I missed your post.

    He did the testing for the army, and then also published the results in the Rifleman (NRA publication, about 1930 or so).
    I can't remember exactly how many rounds they fired per rifle (as I recall it was over 1,000), but the weapons were treated normally for the Springfields.

    I agree that thin barrels are more often than not sleeved. His experiment was solely to figure out how much "meat" you needed to use the rifle without fear of barrel failure.
    Clearly it wouldn't apply to all steels and all calibers. But at least it's something that has been explored in the past, and the results recorded and published.

    Thanks for the added info. Arms/barrels have come a long way from Chinese hand canon and blunderbus, their users would probably think "our" barrels are too thin. Lol

    Being able to make small parts is an important aspect of being a gunsmith versus a tinkerer or parts installer.

    Some of the first cannon makers were also casters of bronze bells and then some people went to iron. The big thing is not the thickness so much as possible flaws from casting weakening the barrel resulting in failure.
