Kinda' like a "hot barrel - high volume" Argentine dove hunt ?
At something approaching a flat of 250 shells/hour, I can tell you
that a Beretta 391 or Benelli SBE or Cordoba can handle that with no sweat.
The barrel WILL get VERY hot however, and you'll soon wear yourself out just stuffing shells into it !!!
Have a look at "Dove Hunting in Cordoba Argentina" in the Hunting Forum. I suspect that fellow probably was shooting
at or over the volume you asked about. Nice pics too !
I have gotten my MM barrel close to red hot, I stopped when the spent shells were coming out a bit melted.
Shot it wet with CLP of course. when I got home I could wipe the carbon off with a rag.
