All,
Criticisms very much welcomed! I very much respect the collective experience of many on this forum -- I seem to learn something new every day. I do agree that I was overly generous with the ranges represented -- no doubt many of us have homes that are smaller and neighbors that are closer. To be honest, I was simply trying to use nice round numbers and ranges that most of us are familiar with. If I had to do it all over again, I'd probably examine/discuss what happens at 3 (bedroom wall), 5 (next room), 10 (neighbor's home) and 100 (elementary school down the block) meters.
Since my original post was so long, would this be a fair summary?
Home-defense rounds:
- 00 or #1 buckshot will cause high damage up close and represents a low/medium risk of hitting those in other rooms/homes (only 6-8 layers of sheetrock; please see previously cited Box O' Truth experiments)
- 9x19mm JHP rounds will cause low/medium damage up close, and represents a high risk of hitting those in other rooms/homes at a close range (12 layers of sheetrock, rounds stay relatively intact), and a low/medium risk of hitting those in other rooms/homes at ranges greater than 50-100 meters (rounds lose significant energy at great distances)
- 5.56x45mm frangible rounds will cause medium/high damage up close and represents a medium/high risk of hitting those in other rooms/homes at a close range (12 layers of sheetrock, but it's tumbling/fragmenting/yawing), and should it so happen to have a clear path/trajectory, represents a medium risk of hitting those in other homes at ranges greater than 50-100 meters (rifle rounds go further)
Home-defense weapons (as distinguished from home-defense rounds):
- 12 gauge pump/auto represents medium/high weight, low maneuverability, and low round count
- semi-automatic pistol represents low weight, high maneuverability, and medium round count (though can get high capacity mags)
- AR-15 or similar variant represents medium weight, low/medium maneuverability, and high round count
Again, as I said in the original post:
when it comes to firearms, everything is a compromise, and there is no one "perfect" or "right" home-defense solution.

Flawed. Your premiss is that a miss at 10 meters (33 feet) and resulting penetration after the miss, is not applicable due to is being only 10 meters. Seriously?

Forgive me -- I think we have a misunderstanding. The discussion/exercise was designed to follow the path of the home-defense round after leaving the barrel of a firearm at three different ranges, using our three hypothetical scenarios, with the bad guy standing in front of a wall 10 meters away from the shooter. If we examine what happens to the round after it's traveled for 10 meters, we stop there -- if it's a hit, great, but if it's a miss, I won't discuss what happens until we get to our next ranges -- what does that missed round do after it travels another 15 meters (25 meters total) and another 75 after that (100 meters total)?

Animoose, in my case where I carry a 44 Spl 3" Bulldog, and a S&W 38 Spl, how does the 44 round compare?

I'm afraid I don't have the expertise to judge that -- again, I was simply trying to discuss the results as demonstrated by the Box O' Truth. They were hyperlinked in my original post.
Thank you all, for the discussion.
respectfully,
Moose
