What's with the "man's rifle" crap? Rifles don't make you a man, big caliber rifles don't make you more manly...in fact, manliness (whatever the heck that really is) is a question of self-awareness. I've been a man for 66 years, a shooter for 58 of them and have a few rifles, purpose-selected as tools to accomplish specific tasks (like target shooting <300 yards, target shooting > 300 yards, varmint hunting, CPX2 hunting, CPX3 hunting and, though not yet, CPX4 hunting). Since Zombies don't exist, I don't have any Zombie rifles, and, since I don't figure to hold off a battalion of anything, I don't have a battalion-holding-off rifle either.
As to your sex fantasies about being a man, try to think on what you're asking and try again.
