I'd put my older Belgie mfg. A-5 12 against any gas operated Remmie self-loading shotgun. Just like with the: M-1 Garand, BAR, M-14 US military rifles with a gas piston, fouling often occurs after repetitive firing, whether from a fox-hole or a duck blind.RWTF
The recoil guns have their own set of problems.
Modern propellants have largely eliminated the 'fouling' problem with auto shotguns. An 1100 run with Titewad or Clays or virtually any current factory shell except the South American garbage will go for an entire weekend of target shooting without any maintenance. It was not always so.
A Garand that stops functioning because of powder residue would be a rare case. Those gas pistons erode, but it takes a very long time and the operating rods can be rebuilt. Competitors shoot their match rifles for years and never take the gas cylinder off or the action off the stock. They purposely avoid that yet the rifles keep running reliably.
