Thank you very much akeedaqhari98!  And you have a point, because you never do see Mr. Norris reload anything.

akeedaqhari98, I am sorry to have to tell you this but I made a mistake.  I forgot that when I tried to make an infinite reloads version of this mod the game would have none of it!  However, I'd did make a similar mod to what you want and  I think you'll like if you should choose to try it.  It's called Ludicrous Capacity Shotguns.  It is available on this website (as well as on the Workshop.)  It gives you so many rounds in ANY shotgun, that it is highly unlikely you'd ever run out due to the fact there are ammo piles in every safe room as well as here and there on every map.  And the ammunition is very deadly to say the least.  Again, I'm sorry I can't give you exactly what you want- I was so grateful for your wonderful reviews that I agreed to your request without thinking first if it was possible.
