I bought some corbon ammo a while back that was sitting around the shop for a while. Anyway I did a lot of testing which I posted here a few months ago and chose the .45ACP 165+P ammo. After carrying it for a few weeks I noticed while swapping mags that one of the rounds had a crack down the side of the brass casing. I checked all the ammo out and replaced it then called Corbon to report the issue (there were a couple that were cracked) and I got more than exspected!!! I found that the ammo was from the mid 90's which doesn't mean much but they still stood behind it. They replaced the 77 rounds I had left with 220 rounds of new ammo! I have never seen a company go to such lengths to make sure they keep a customer happy! +1 to corbon they are an awesome company!!!!
