They can't legally sell surplus military ammo intact. There's a reason too for the ammo to be disassembled. Either it is too old, has been tested and does not pass quality standards, hasn't been stored properly etc. Pulled bullets are most often said to be collet pulled, air pulled, or machine pulled. Collet pulled and air pulled does not damage the bullet but machine pulled has fingers that grip the bullet and pull it from the brass. The fingers can and does leave gripper marks, cuts, and raised burrs, and can even squeeze the bullets out of round. Machine pulled bullets should be resized either by the seller or by yourself with a bullet sizing die in your press. Commercial ammo manufacturers sometimes sell their pulled bullets too. Commercial pulled bullets most often aren't damaged except for showing a crimp ring where the bullet was crimped by the factory. You see the crimp ring on pulled pistol bullets often in calibers like 9MM, 40S&W, and 45ACP which uses a taper crimp die. Look closely at the sellers explanation as to how the bullets were pulled and decide if the cost of pulled bullets is enough savings versus new bullets to justify buying them in the first place. Pulled bullets often are good plinking bullets but not the best for accuracy. Pulled bullets come from several different lots of ammo, often show different base shapes or tip shapes, weight often varies more than new, and can even be from different manufacturers. So just see if the cost savings justifies buying them. I've bought .223, 30 caliber, and 50 bmg surplus pulled military bullets and have gotten some very good lots and some not so good.
