My DW and I both have 9MM CZ-75s and Henry rifles (a Golden Boy (Cal .22) for her and a Big Boy (Cal .44) for me. We also have a Ruger Blackhawk with cylinders for .38/.357 and 9mm and a Beretta .22 target pistol. We are members of a shooting club in Kingman, Arizona, and burn a lot of ammunition putting holes in paper targets.
I used to order in bulk from Cabelas (those extra plastic ammo boxes are great) but now I don't see any bulk ammo pages on their web-site.
Bummer.
