62gr M855 or 55gr M193: Must choose ONE or THE OTHER for 16" bbl 1:7 twist

[lysander]

Yeah but those are marketed as 193 clones. I’m talking more about PMC Bronze, AE .223, and others that are bulk 55gr .223 instead of 5.56 like 193. I thought Wolf Gold fell into that category as well.

Commercial "ball" probably has more variation than military ammunition. But, I'll bet that all 55 grain .223/5.56mm stuff is around 3,100 plus/minus 150 fps on an average 70° day.

This is a good find and counter to what I thought I had seen so I appreciate the correction. It’s worth noting though, that his test barrel is a 20” just like most manufacturers, so most of us will be seeing a lot less, especially with SBRs.

I’m still working off assumptions though, I haven’t chrono’d any of the cheap stuff so the few unscientific notes I have from personal experience is mostly around 77gr stuff.

How important is velocity and terminal performance? From AA reports I would say it needs to be considered for combat rifles. Some barrels like the 5R and 3R rifled barrels are known to produce more velocity from the same length barrel, some 13" are faster than BCMs 14.5s(enfield/square rifling) and very close to BCMs 16", the 16" 5R/3R are almost as fast as the 20s.
I'm getting 3030fps out of a 13" ARP 5R barrel with IMI M193, my BCM 14.5 gets ave 2956.

Does this mean m193 is a good 100 yards, 200 yards, self defense round?

That depends on what your definition of a 'good self defense round" is.

From my experience I have no worries using 223/5.56 ball ammo for self defense. That being said, there are obvious benefits using a purposely designed bullet and my main defensive ammo is such.

THIS! 62 or 55 gr ball ammo can be HIT or MISS (so to speak) depending on which crock of crap example/test you choose to believe. Why not choose a premium defense ammo? Christ! We almost never even use 55 or 62 ball for slamming steel at short range. I had to dig around my bench for 2 days to find some 55gr FMJ last month so use with a pound of benchmark I grossly overpaid for.

When I do use a range with known distances, it's private. The first steel is at 300 and goes out from there, precisely to mitigate damage from FMJ. Everything inside 300 is consumable materials, plywood cardboard etc. Where I mostly shoot, it's dirt clods, rocks, and tree stumps also private, shoot what ya got.

Agreed. I have Speer Gold Dot 62gr and 75gr in my home defense magazines, but if there was a need, I would have no worries using m193 for self defense.

Almost anything coming out of a good .223 rifle will be formidable. But when we have the luxury of picking a nice bonded or OTM, running ball is just cheap or lazy. Even if you just fill one clip with over-bred ammo, and run ball for all else, you're wise.

Wolf soft point is damn good ammo for self defense unless your rifle malfunctions with steel cased. Check first.

And Google it.

Define “damn good” then ask yourself if good bonded or OTM ammo isn’t “damn gooder.”
