Head over to gunbroker.com. They had several boxes available... last price I saw was $350 a box. So, pick up a few boxes LOL
Here's one of the things that I've started to see at an alarming rate... people "reviewing" or "testing" guns, gear, ammo, sites, etc.. what makes them the best qualified person to be passing judgement on all of those things?? Make sure you know who's feeding you info. In the last two months I've been all over the country (and out of the country as well) and I've had the privilege to meet and hang out with folks from various industries and various backgrounds. Some have started publishing "reviews"... this is nothing more than what THEY feel are the strong points or weak points of whatever they're reviewing. Most often, many people disagree with their view, but oh wait... it's published on the internet and they claim to have lots of experience, training, etc.
Bottom line, read, read, and read more. And then, do your own research. Since I dont think we have any ballistics experts on this site (please.. correct me if I'm wrong), how will you interpret the data that is shown, once "independent" testing is done?
Don't drink the kool-aid before the party. Do your own research.
