Oh well, here goes again.
Here is what Mr. Ayoob recommends.
"At LFI, we suggest buckshot. It has proven itself over the years as the optimum close/intermediate range antipersonnel shotgun round.
Birdshot can still go through sheetrock. One does not minimize danger to family members in other rooms by using birdshot; one does so by working out a coordinated defense plan that will not have one firing in the direction of other household members. If the armed, identified intruder ducks behind a wall or piece of furniture or other barrier, you WANT to be able to reach through and hit him."

BTW, the important thing to get from that thread is that prior planning with an understanding of Fields of fire is much more important than loading.
Mr Farnam recomends the following
"We recommend 00 buckshot in the standard, nine-pellet loading. Federal, Remington, Winchester and other reputable manufacturers produce this load in great abundance, as it is the standard used by most law enforcement departments. Other sizes of buckshot are acceptable, but 00 renders the best performance. We do not recommend any of the magnum shotshell loading, 2 3/4" or 3". The magnum loadings are very uncomfortable to shoot and offer little benefit in return. We do not recommend birdshot and other reduced-recoil loadings. You need to practice shooting the real thing!"
Mr. Izumi recommends #1 buck.
When working pre-hospital in Shreveport I responded to a call in which an attacker was stopped with one shot to COM with a Davis 22. He was very dead by the time we arrived on scene.
Therefore, based upon some of the logic in this thread, the Davis 22 is an ideal self defense handgun.
No, it worked once, that does not mean a 22 long rifle is a reliable stopper.
I have two questions for those of you who recommend #7 1/2 Birdshot.
Are you basing this recommendation on experience and or training? Do you have any experience or training?
Do you have any experience hunting with a shotgun?
For those of you who don't understand the difference in shooting to kill and shooting to stop. I highly recommend you take a course in self defense. It has almost nothing to do with the load you select. It is all about state of mind and intent.
