Probably a total of 1,800 or so I'd venture to guess. It was mainly just a torture test of the Smith and Delton to see how long they'd run till malfunction with the steel cased ammo.I've read good things about the Nitride, Melonite ect. Only it didn't hold up to heat as well. My latest one has a Nitride coated barrel. And was actually thinking of sending in the WOA barrel for treatment.
Good to know your Smith is still accurate. How many rounds of Russian ammo did you run through it so far ? Were you using Tula when you did your testing ? Sounds like it has a lower chamber pressure.
I found a picture of the casings that stuck in the Delton. Bushmasters and Colts didnt like them either according to the article. Smaller gas port.

The Smith never did fail, and went over 1,000 consecutive rounds but was getting very sluggish. The Delton stuck a case or two at around the 420 mark IIRC.
