You will never have a problem with either round in that rifle. 5.56 and 223 are both offered in many weights, from 35 gr. up to 80 gr. If this rifle is a 12 twist it will probably be more accurate with bullets in the 55 gr and under weights. It might shoot some that are slightly heavier ok, you'll just have to shoot it with different weights and see.

Does anyone have any info available to them confirming what round if any the .223 weapon is capable of firing other then.223?

The 2 are the same round. The military calls it 5.56, civilains call it 223. The military does load their ammo a tad bit hotter and uses looser chamber tolerences in their rifles to promote better reliability. For all practical purposes they are the same. While some get all upset and try to claim they are 2 different rounds no one has ever provided any evidence of a problem although 90% of shooters have no idea of the supposed difference and use them interchangeably. At worst some semi-auto rifles may not function with 100% reliability.
