I think the bigger issue here is your stepson is a grown, working (law)man who should be able to afford to buy his own ammo. If not, HE needs to figure out how to get what he wants/ needs and can afford.
I agree 100% and would think twice befor loading ammunition for someone else.
I once bought a bad brick of primers that were recalled by Remington. The problem was my bolt face was badly etched before I knew the primers were bad.
Also loose primer pockets on a over gassed AR15 can also be a big problem.
I found the photo below in a AR15 forum and its food for thought.
And how will your relations be with your stepson if his bolt face ends up looking like below.
I was given three five gallon buckets of .223/5.56 free brass fired by our local police. I gave up using much of these once fired cases because of quality problems and loose primer pockets. And the biggest problem with Federal cases was over sized primer pockets after they were fired once.
Below you can see the difference in the thickness of the flash hole web in the Federal cases.
I now buy bulk once fired Lake City 5.56 brass that is collected from the military. The Lake City cases are made of harder brass than commercial .223 cases. And have thicker flash hole webs that add radial strength to the base of the case.
The harder brass came about after the 1968 congressional hearings on the M16 jamming problems.

Bottom line, the .223 is rated at 55,000 psi and the newer 5.56 M855 ammunition has a max chamber pressure of 58,700 psi. Meaning the Lake City 5.56 cases are made to withstand higher pressures. (built Ford Truck Tough)
