BudsGunShop.com - Are the primers staked/crimped in?

Yes.
This 5.56x45mm NATO Ammunition is manufactured by Australian Defense Industries to NATO specifications and is comparable to SS109 and M855 ball projectiles. The 62 grain F1 Ball projectile is made of a hardened penetrator and lead slug enclosed in a gilding metal jacket. Under the bullet is a single based propellant that features very low temperature sensitivity and is extremely clean burning; making this ammunition accurate through a wide temperature range. The ammunition is first quality, new production ammunition, loaded in boxer primed, reloadable brass cases with Mil-Spec crimped sealed primers and sealed bullets. Each round is in the bright, pristine condition as the day it was loaded. There is no patina or tarnish - even the annealing coloration on the brass was removed before loading!
This ammunition is packaged in sealed 5 round packs with 10 packs per sheet. Each M2A1 .50 Caliber ammo can is sealed with 18 sheets. This ammunition is ideally packaged for long-term storage.

Sean, these are military rounds with crimped primers Sir. Cheers and stay safe!
