Best Ammo for Defense?

[Olympus]

I apologize if this has been asked and answered a hundred times. I've read so much that I can't tell which way is up. I'm looking for some factory ammo options to load up several mags for dedicated defensive purposes. I've read a lot of things about M193 being superior because of the speed, but some say that needs to be out a 20" rifle to be effective. Others have said M855 is better because of penetration. Others have said factory hunting loads with ballistic tips like Hornady SST or even Federal Fusion. It's hard to sort through everything and determine what I really need.

Should I just load up several mags with M193, M855, and maybe a few factory hunting loads and just mark the mags so I know what's in each one?

M855/m193 for practice. Use a good defensive load feom “the list” below for sd/hd.
I use fusion 62 gr and run a few mags to test accuracy and verify poi before staging mags.

That said, ammo choice doesnt matter if you cant shoot, so make sure you train.

I wouldn’t bother wasting the money on 855 for practice. 193 all day for plinking.

.223 and 5.56 rifle ammunition has such velocity, energy, and effect that at close distances it's almost hard to make a bad choice. However, widely available data makes it easy to make better choices. Where unobstructed shots are expected and penetration of backstops and downrange hazards are of greatest concern, a lighter weight, lightly jacketed rapidly expanding varmint, OTM/HP, or some JSPs are a choice. If you expect barriers get stouter bullet construction like bonded SPs and copper solids, and certain heavier JSPs and OTMs.

Service ammunition in common use, subject to terminal ballistic testing, conducted to standard, and meeting recognized performance standards, offers the greatest flexibility and defenseability. Learn what your ammo does, to what, and when. Practice with it and place it accurately on target.

People use the label "M193" a lot. Remember that M193 is a particular round with an established specification and accountability. Most of what people call M193...isn't. It's 55 ball of some sort. I have used genuine and imitation M193, but learning occurred and I choose better.

Most manufacturer websites publish lab-grade gel shots and data on their LE/defense loads. Vista, Winchester, Hornady, Black Hills all have gel data online for viewing, and some will disclose more on particular rounds if you call and ask about a particular need.
