I have an Aero Precision stainless 16" fluted barrel in .223 Wylde. I know that the Wylde barrel is supposed to be safe for both 556 and 223

BUT

I also know this ammunition

Is sligtly hot compared to the average 556 round. So the question is would there be a safety issue using it?

I called Hornady and they would not say yes or no and were actually unsure of the chamber pressure the ammo would produce. I was told no less than 58,500 PSI and no greater than 61,000 psi.

Wylde was designed to handle 5.56 pressures (62k psi), while shooting .223 with much better accuracy than a 5.56 NATO chamber can generally do.

You are fine.

You're good.

I appreciate the feedback.

After reading and seeing fractured guns I am a little gun shy on hot ammo.

Taking precaution with dealing with firearms is always a good thing.

Better to ask than show your ER pics!

Kentucky Ballistics comes to mind

Well I just bought 500 rounds. Hope I can hit what I need to regularly at 600 yards.
