I have a fair amount of Winchester White Box ammo in storage. Well over 1000 rounds each of .45ACP, .40S&W, and 9mm. I bought it back when it was reasonably priced. Lately, since I started reloading, I've been thinking of selling it. Are there any MA laws that prohibit this? Should I just hold on to it? My guess is that it's like money in the bank and will only appreciate in value.
