RE: iron sights
I have a winchester .30-.30 and a winchester in .44 mag. Lever actions. I use them both as "drive guns" for when I am driveing for other people. I have killed lots of deer with both. Love open sight hunting. I never have any problem finding deer in a scope, but having open sights is another fun way of hunting. My personal limitation is about 50 yards with the .44 and a 100 or a little more with the .30-.30
