I think a .410 shotgun SbyS would be a great starter for a ten year old.

I started carrying around one of these when I was about 9 or 10. Then later a single shot .22 rimfire.

My first rifle of my own was a .222 at about 16. Then my ,30-06 year or so later. Believe it or not, turned down a .375 H&H Double Rifle for $1100 back then, because I wanted something bigger!

Reckon a .410 would be good for a young kid. I don't believe in spoiling kids. Make them work for the special things in life.

Good attitude re guns by the kid though.
