Do you REALLY have a valid reason, or did you just want to post a nice picture?
A 10/22 is an excellent all round weapon. Shot guns are limited by effective range. A well placed shot with a 22 is devastating and can bring down about any averaged size game including deer (Using scopes and a head shot) It can also wreak havoc on humans and be waay more accurate at range then a shotgun.
Granted bigger rifles are better but when you have limited funds an 870 and 10/22 for everyone in the family is cheaper and highly effective for protection and hunting if the SHTF. (And you only need deal with to types of ammo.)
