Have grandsons age 7 & 8 that are ready for their first rifle. The Red Ryder has lost it's luster. Topic has likely been discussed before, but I am looking for suggestions for their 'first rifle.' Thinking a bolt single shot, maybe something like a Henry Mini-Bolt, etc. Also plan on starting with open sights. Would like to set-up a range for the g-kids to practice on, one g-kid at a time. Any tips / suggestions will be greatly appreciated. Thx!
