I too came across a Winchester 1400 Ranger 12ga about the same time as the OP. Got it from a co-worker for $175. He had never shot it.
I've put about 400rd of Winchester x target loads through it.
It doesn't say on the barrel, but how can you tell what choke it is? It came with a screw in choke but took it out and now I can't hit anything with it (trap) so I'll but it back in for trap league tonight.
I figured it would/is a good starter Shotgun and move up to a Higher quality ? gun later.
