for me it depends on the brush situation. In heavy brush I often get only running shots, so I use a shotgun in those areas. Also depends on hunter habituation. Hares prefer to sit tight and let their camouflage work, so .22 is very effective and will ruin very little meat. Shotguns can be pretty messy.Do folks use shotguns when hunting these hares or are they mostly still shots with rimfires?
Or is it just a matter of personal preference?
