Well, I've shot and more than once between 300-500 in a day, and within a couple hours on a couple Beretta's autos and never had a problem.
Have shot a little over thousand in a day and worked at it, also with no problems. Have run the Beratta autos over 5000 with nothing more than a oil spray into the action and sometimes an oil rag wipe down on the tube.
Same thing with O/U's and the ejectors kept kicking them out with no problem. Heated the metal fore end release on a Krieghoff and Perazzi hot enough you wanted to set it down and hot enough to turn the inside edge of the forend dark.
Same with an old 870 Wingmaster, but never in that quantity. But the chamber on that shotgun hasn't been brushed or scrubbed in years other than a finger oil wipe on occasion.
Ammo a mixture of Winchester's, Remington's, Federal's, Rio's, Cleavers and a bunch of others.
Certain gunsmiths have also mentioned things I don't necessarily buy but will admit a clean chamber certainly wont hurt anything.
