It ain't quite "malarky", ElectroMotive. The VAST majority of CCW combat occurs @ short distances (under 7 yards), and is over without a reload.
I didn't make that up--I learned it from Massad Ayoob.
If you didnt make anything up cite case law, or for that matter penal code that has distances mapped out. It doesnt matter what Massad Ayoob says, because to be quite frank, I dont trust him at all.
You go ahead and train for 7 yards and no reload. I'll train for the worst and hope for the best.
While ANYTHING is possible, IMHO the chances of an ordinary citizen (not a gangbanger) facing "6 or more opponents" is far fetched. In over 50 years of shooting and reading about weapons and gunfights, and over 30 years of training people as an NRA Certified Instructor, I can't remember coming across even ONE such incident. (doesn't mean that there isn't one--BUT it is rare).
Here in Texas a CHL holder fired in defense of a Dallas cop from 75 meters away. No charges. In the "Arizona" a man used a SA Ruger in .44mag to stop a home invasion, firing at the last badguy at over 50 meters. My neighbor in Dallas used a Colt Trooper to shoot at a fleeing car, firing 6 rounds, at well in excess of 75 meters. No charges. Also here in Dallas, 4 years ago a guy fended off a home invasion, killing 5 of 6 armed and ARMORED badguys with a Polish AKMS (AK underfolder). No charges. Able Walton in West Dallas, fired in defense of his property 3 times in one week, killing 3 bad guys. No charges. You might claim, "well thats Texas", but you must realize we have a liberal DA, liberal sheriff, liberal police chief, etc. Island of blue in a sea of red. All of these events happened in the last decade
Keep and Bear Arms - Gun Owners Home Page - 2nd Amendment Supporters keeps a fairly accurate list of self and home defense shootings. Multiple assailants are in almost half the shootings they report on.
The big crime story in Houston, TX is the alarming amount of home invasions and muggings taking place with multiple armed men, wearing police style uniforms, and body armor. KHOU TV is the source.
In any event, I like your choices of ammo. I carry a 686+ and a 642 loaded with Speer 135gr Gold Dot +P, AND 12 additional rounds in 2 Bianchi Speed Strips everyday. Your "duty" in a hostile confrontation is governed by the laws of the jurisdiction wherein the incident occurs, and may depend upon such factors as the existence and extent of "the Castle Doctrine".
I agree your duty is to adhere to the laws set in place. That said I've never seen a law that states shooting in defense at 25 yards will get you thrown in jail. For that matter I've never seen a law that states distances at all.
