Just a note that everyone should try to use USPS Flat Rate Boxes when using Priority Mail to ship heavy items AKA Ammo. If you use your own box the price can double. Recently did a trade for 2500 slugs. I shipped 11 Tins of JSB King Heavy in .25 for less than 1/2 what it cost the other party to ship me the slugs. I used a Large Flat Rate Box. He used his own box which also had a dimension over 12 inches (cost goes up for that too).
