My wife is one of those!! ha When I mentioned that I found a guy nearby that would sell me 4225 rounds of .22LR for a great price, her comment was "Why do you need that much ammo?" followed by "I don't get it."Some people just don't get it!
I got 20ga, 30-30, 35 Rem. and .308 in the other closet...she hasn't seen yet!Your GF is right. What is wrong with you, man? You don't have any rifle or shotgun ammo!
I don't see any .44 magnum or .45 ACP ammo. You need to address those issue promptly otherwise you will always be considered a neophyte.
