Of course, you have to have 2 of everything, just because you have (or should) have 2 handguns, you will need 2 shotguns and 2 (or more) rifles.
Also need a bigger ctg. rifle for the 'Sunday" challenges.
I cleaned up on one of those, with my Uberti .50/95 Model 1876, knocking over 12 sil's (one loading) from 50 to 200 meters.
