3" #2 shot. Probably alternate lead and steel. This BLM stuff really put the kaibosh on my 2x 20 gauge semiauto for home defense plan. Trying to wait until things normalize. I can shoot a 20 gauge semiauto with 1 hand. Why not have 2? One for each hand. You can fill a room with lead and not have to worry about the neighbors too much.
Keltec has interesting things with crap accuracy. In an indoor environment, I would go with maximum weight that does not exceed the sound barrier and the most pellets. (up to #4) The last thing you need to be dealing with in a stressful situation is a concussive blast generated by you.
It really doesn't make a difference, what counts is shot placement, a single pellet, hitting the correct location can do the job.
I think you're ignoring the ability of buckshot to penetrate walls. You're lively overestimating the spread of shot at across the room range.
Ask any decent instructor how this would work and they'd say "not well". Even with a pistol, you should use a two handed grip to maintain focus and control. "Filling a room with lead" is not an effective method for home defense. Discipline, focus and tactically reloading when using a shotgun is the way.
I think you did not consider whacking the perpetrator in the head with a piece of steel like a pipe. You can then pull the trigger if you want to or not. As to whether it blows his head off or not, is entirely up to the wielder. You can go do some calculations, and then realize what I'm saying is true.
Someday if you ever get down this way I have a house we can go into, you get two shotguns, I get to surprise you, I'll bet a steak dinner when it's all said and done I will have one or both of your shotguns before it's all over. I teach weapons retention and can disarm most anyone who isn't properly trained in retaining a weapon, more so when it has a long barrel. When it comes to money and guns leverage cab a friend or foe, depending on who is the one being leveraged.
Really cool shotgun, but damn the Russians aren't much for fit and finish. Looks cobbled together with stuff they found somewhere.
A lesson I learned as a kid came back to me not long ago in regards to birdshot and close range shooting, the element of "express returns". Out in the country just blasting stuff, I decided to see if the birdshot I was using could punch a hole through a 50 gallon burn barrel we had. It certainly did however just the majority of the lead continued traveling whereas the pellets around the peripheral of the hole it punched came back with a good deal of energy still. Felt like bee's all over me, lucky I didn't shoot my eye out. Birdshot is for the birds.
when I worked for the DOJ, I was given some federal tactical buckshot. I later was part of a team that tested a couple then state of the art tactical shotguns for a now defunct magazine. One of my team members had some connections and got 1000 rounds of that stuff in #4 from federal. I have been a fan of it ever since
many many years ago, my college skeet team practiced at the university's "outdoor education" facility that had fly fishing ponds, and the forest that the school of forestry used. When the varsity practiced, one of the fly fishing ponds was closed-or so we thought. The captain of the team was on the 76 Olympic team and had been on the world championship team in 77. The fall of 78 we were practicing when one of the professors started fishing on the closed pond. Our captain politely noted that the pond was closed but the professor noted-its only birdshot and "I am 100 yards away". Our captain looked at me and said-hey, you got that knife you always carry and I handed it to him. He said, this is what we do about jackrabbits in Texas (where he was from). He ringed the shell. when we got to station 7, he said-throw me a low house. That ringed shell hit about 20 yards west in the pond where the professor was fishing. I think the guy jumped in the water. SORRY yelled the captain, winchester must have put a deer slug in my skeet shell box!!
