I do know that there is nothing on either TSA or Delta websites restricting the cartridges from being inside a magazine... I have read several scenarios on blogs and other forums of accounts where TSA forced a passenger to miss their flight because the loaded mags "raised a red flag".

From TSA FAQ

Ammunition
•Ammunition is prohibited in carry-on baggage, but may be transported in checked baggage.
•Firearm magazines and ammunition clips, whether loaded or empty, must be securely boxed or included within a hard-sided case containing an unloaded firearm. Read the requirements governing the transport of ammunition in checked baggage as defined by 49 CFR 175.10 (a)(8).
•Small arms ammunition, including ammunition not exceeding .75 caliber and shotgun shells of any gauge, may be carried in the same hard-sided case as the firearm.

I flew Delta 3 weeks ago. Ammo in mags is legal and even stated so in the FAQ. They are indeed special tagging the bags and tie wrapping them upon arrival where you cant open it. Another feel good annoyance that literally stops nothing. Also, you have to get it from the lost baggage counter. IAH if you are wondering.
