Skychief - I may have no memory but my computer, Hal, still does.
I'm glad you are enjoying that Southgate. I had wanted one since I saw his American Rifleman article in 1952. Cash was not so available then, so I stayed with my Red Ryder. The rifle I sold you in 2011 was just fine but my arms are too short & my left shoulder lacks the strength to hold it.
Yours is No. 507, the Dixie list of serial numbers says it was built in 1959. At that time I believe Southgate was rifling his own barrels using cold-drawn octagonal 1018 steel blanks 48" long, either direct from the mill or from Dixie.
Others on ALR may wish to comment on this.
I told you it was .41 caliber, perhaps because that was what I was told. I wonder, exactly what caliber did you find it to be?
I have made rifles using .50 cal 7/8" cold drawn 1018 from Pa Keeler. That was before I learned that seamless tubing sometimes has a crack down the bore. Never heard of any of these barrels blowing up, which only means I never heard of it. Well, if yours has hung together this long there probably is no crack in it. That 1018 steel, even cold drawn, has pretty good ductility across the grain.
Yeah, I would have, and still would, shoot it if I could hold it.
I recall that Bill Large was most insulted when Muzzle Blasts published my Oct-Nov-Dec 1985 series on barrels. Never heard of any problems with his barrels, the only one I saw had been ringed near the breech for some reason. Personally, with all respect to the late and legendary Mr. Large, I'd not care to use them.
Searched for my 1981 LaSalle Steel Co. data on STRESSPROOF (their 1144) and LA-LED (their 12L14). Data for both is frightening, considering that some people think they can use them to withstand high-impact loading (an explosion is high-impact).
There is an old article in the Single Shot Rifle magazine about an 1144 barrel failing, I think at an extractor cut in the breech. Not such great fatigue resistance (cracks if loaded thousands of times when there is a notch present).
Enjoy No. 507, Mr. Skychief
