Tyrone,
You can hand-load to any COAL you like, as long as (1) the pressure is at or below SAAMI, (2) the bullet does not jam into the lands when fed into battery, (3) you are prepared to hand load the longer one's individually into the breech, and (4) you have enough bullet shank in contact to keep it from moving, especially if it's being auto cycled.
Having to load shorter increases jump-to-lands, which in an AR is already longer than precision bolt guns. But, it is an auto loader so par for the course. Plus it won't have too much influence on precision in that type of rifle. Unless you are shooting very competitive competition, and those guys hand feed their overly long 223 rounds into the breech anyway - even with spec mags.
If you don't plan on returning the mags then you can still use them - just load shorter to fit and watch those concerns. To be fair, the mags should at least be SAAMI 2.26" and unless the factory ammo you buy is 2.21" or shorter then you are stuck with hand-loading. Some stainless mags can take 2.28" because the walls are thinner.
Never used that powder so someone else might be able to help with pressures.
