What is the oldest defensive/carry ammo you have? I think mine would have to be some DoubleTap 10mm I bought 6 or 7 years ago. At the time it was the most powerful/potent stuff you could buy for 10mm and I'm pretty sure it still is. However, all of my 9mm and .223 ammo has been rotated brand and model-wise every 2-3 years. Does anyone have ammo they bought 10+ years ago and still rely on today? I only ask because in the world of ammunition it seems like carry/defensive ammo is BIG business and just like other areas, new stuff is coming out all the time so older stuff is often quickly out dated. If that is the case, then why bother buying more than a box or two of what you will use? It will only be obsolete in a few years...no? Thanks! -Emt1581 Wanna kill these ads? We can help!
