Well, All of you youngsters call those old pumps and semi-autos "Grandpa guns". I am a hair older and my Grandpa taught me to shoot with his guns, which were L.C.Smith side-by-sides.
He had me shoot the old twist gun with low base shells and light loads. It also had a set of hammers and he felt I was safer with those (even if he didn't know the gun might blow up). I still have the old gun, but his hammerless "Elsie" got away, but I do have a really tight and clean hammerless like he had. I try to let it take a couple of birds each year. It shoots really tight for just modified and full but I attribute that to modern shells. Some friends refer to it as "Old Grinder".
