Lots of great, older, Winchester pumps available. Unfortunate you are not considering the Remington 572, I've yet to find a bad one, they are accurate and reliable, with shorts, longs and lr's.
The older Remingtons tend to be a bit more accurate than the Winchesters.

Imagine your grave on a windy winter night. You've been dead for 70 years.
It's been 50 since a visitor last paused at your tombstone.....
Now explain why you're in a pissy mood today.
