welcome to the site
you will get more suggestions starting a new tread asking your question, rather than in an old tread like this

if you give us a ball park on how much you plan to be able to spend, we can offer some suggestions

and a little more info on HOW far you like to shoot at expected game
and last, welcome to the site

I plan on shooting from 25 to at least 300 yards and price range is atleast $300.

Shotguns need red dots IMO
