Is there really a difference in quality or accuracy between the PMC 55gr rounds in .223/5.56, as shown below?

I've purchased 1000 rounds of the X-TAC 5.56 rounds in the past, and I've had good experiences using them in my rifles and AR pistol. However, everywhere I've checked they are out of stock and some places said they were no longer going to carry them (are they being discontinued)? I can find the PMC Bronze rounds (same specs as the X-TAC) for the same price as what I picked up the X-TAC for, and they're in stock everywhere. My barrels can take either round, but I just saw more people saying to get the XP193 rounds in the past so that's what I was getting.


Is there really a difference between the .223 Bronze round and the 5.56 XP193? Or will I be just fine with the PMC Bronze? I plan to plink at the range, but to mainly stock up and save the ammo for my SHTF stash (and for an Obama re-election, if that happens). So I'd rather stock up on something that would be better in the long run for multiple uses.

There is a difference, the XTAC is a hotter load and chambered in 5.56

I think this place has both in stock.

Further:

X-Tac 5.56 ($0.02 more per round per box at site mentioned above)
Muzzle Energy:
1306 ft lbs

Muzzle Velocity:
3270 fps

The .223:
Muzzle Energy:
1250 ft lbs

Muzzle Velocity:
3200 fps

Above info from the site in previous post.

Don't think you'd notice much difference punching paper...$0.02 suggests give it a try and se how your rifle likes it and if you get any differing results.

Besides one being 556 and the other 223. The 223 is a boat tail bullet which imo is a better projectile then the flat base. Better accuracy at longer distances and they retain velocity better than flat base

Both of those rounds are using a boat tail bullet.

One thing I found with the PMC Bronze 55 grain stuff, it's filthy, dirty! I shot 2 boxes of it and went home and sold the 500 rounds of it I had stashed. Then I spent an hour cleaning my rifle.

XP193 seems comparable to Lake City M193 loads. 1.5 MOA benched 3-shot groups for me.

I guess XP193 is not just a marketing term, but the manufacturer is implying it adheres to M193 specs. I think under 2 MOA 10-shot groups is the norm for current Lake City made M193.

Well I just went to big5 and bought about 200 rounds of the bronze stuff. 7.20 a box.
