For inside the home, I think anything between #4 and #1 is best.
Police also use ammo not to kill an attacker or suspect, but to subdue them. That's why they always used #4 buck: it didn't penetrate deep enough to kill, but it did enough to stop or slow them.I'd tend to agree, unless you have a REALLY big house. My house is small and the longest possible, albeit unlikely indoor shot might be 20 feet. The idea that somebody will take a blast of #6 center mass at 20 feet, and will be "angry" and continue an attack brings me a chuckle.
Police choose ammo in preparation for scenarios with distances beyond the length of your hallway.
Sorry, you're right. I meant to say it doesn't penetrate the 12" FBI minimum, so it's less likely to kill than larger buckshot.Where did you read that #4 won't penetrate enough to kill? That is a big old load of horse-pucky. "They" use it because it only penetrates enough to subdue an opponent but not kill? Seriously? Come on now.
