A lot of excellant suggestions here, all have merit. A youth sized bolt in a light caliber may be the most practical.But to me being a nostolgic kind of feller, I'm going with a mod 64 30-30. Building a deer rifle for two 10yr old grandsons. Had an old mod 64 in rough shape but definetly a shooter. Barrel shortened to 19in, added a pachmeyer de-cellerater recoil pad with stock ending up 1in shorter than origonal then cerakote finish. Just something american shooting your first deer with a 30-30.
