Sorry, but I will trust my own observations, over a period of nearly 40 years, as to the effectiveness of various loads for HD, as well as the reports of reliable organizations, such as the Firearms Tactical Institute, the FBI, and various LE agencies, over your observations.
Good, then my link above to the Brassfetcher testing, including photos and very complete detailed information, showing that the test results of #4 buck meets all of the accepted requirements of penetration ought to be enough to get you see that #4 is perfectly acceptable and in some situations is actually preferable. But I'm sure you'll continue to spout that the only answer is LE132 1B, as you've done in multiple threads.
At 51 yards are you advocating #4 buckshot?....
What? Are you having trouble keeping up with the conversation, or are you deliberately trying to put words in my mouth that I never said or even implied?
he should be using a tighter patterning load than #4 buck
Like using a choke, which you scoffed at earlier? Funny, I have #4 loads that will outpattern #1 loads at any distance in my gun.
he better be able to afford a damn good criminal attorney if he misses (there is an old adage, "there is a lawyer attached to every pellet.")
Again, overpenetration concerns are exactly what we are talking about using #4 for, and you have given more validity to it with this statement.
Perhaps better advice from you would be to obtain professional training and become proficient with a shotgun.
While that's advice everyone should take, that's not what we're talking about here. My advice is to choose your load based on your gun and your situation. Oh, and not to listen to those who state one particular round is what everyone should be using in every situation in every shotgun. Of course, that's something people who have actually gotten training would have learned, so maybe that advice stands.
Again, I'm NOT saying #4 is the best. I'm saying that it works, and there is evidence that backs up my claim that it's proven to work, and there is NO proof that it DOESN'T work, and your statement is based on one website's analysis of other peoples info, and one website where some guys shoot stuff in their backyard. Basically, you don't have an argument valid enough to convince anyone, and you're just coming off as a #1 buck fanboy.
Unless you can quote a statement from a person who survived a proper hit of #4 buck at home defense distances, I wouldn't tell anyone that is isn't an acceptable choice.
