It sounds like your Remington was older than mine. 
 
That .22 and 20-guage combo would be more all-around useful, but then it is lacking for shooting large game, especially at distance. But it would be a better choice for the person who could only have one gun.
 
My uncle had one of those combo shotgun/rifles. It has been so long I do not remember exactly what it was. I believe it was a 20-gauge shotgun, and it had a rifle round that I can't remember. I think it might have been a .44 magnum. But that wouldn't be my choice for a rifle round.
