There some nice ones out there from 1980s. Two come to mind 7-30 and .307. The 7-30 is 7mm slug in .30-30 case and 307 is rimmed .308. I'm sure both can be scoped and Leupold 1,75-6x32 would be just about perfect for the job. The 24" barreled 'XTR' 7-30 rifle with long magazine tube would also make very nice HD gun. Something to consider because when Madam President takes over in January assault weapons and high cap hand guns might be banned in USA.
