You can get FACTORY Mini 20-rounders at Midway for $30.
So not that hard to find and pretty much the going rate for any hi-cap pistol magazine I've purchased recently.
I've had the good opportunity to shoot all of the above options plus ARs and lever action 30-30's.Both are great rifles and I won't say anything bad about either. (In fact I'd love both.) However, if the primary role is 'ranch rifle' get the original, a lever action 30/30. Win 94 or Marlin 336, your choice. Find one for $300 and use it until you decide what semi-auto you want. Obviously I'm no operator, but the old school still works.
