I was asked how I got 8ga heavy barrel so quick.
First it is smoothbore, second a 110 bucks total shipping and all.
First I bought a 1.5 inch dia 4130 alloy, heat treated, shaft,
32" long. Then I had a deep hole drilling company drill
a .832" hole in it. Came out centered on both ends.
Then after it got here I used cylinder hone to polish
the inside of the bore. Threaded it, chambered it, and put
in the Enfield bolt action. The heat treating it had was just like
the barrel stock that barrel guys get. Ed.
