I have been talking with someone out of state who both of us want to swap LRP for SRP. A win win for both of us.
But, what’s the word on using a shipper?
I’ve seen primers for sale on gun broker, and midway and cheaper than dirt have them listed for sale (out of stock) in the past, so they must be able to ship some how.
Suggestions?
Just put them in a box and mark them “cookies” and fragile. 
Sounds like more hassle and cost then its worth.
You cannot ship primers without a hazmat license/certificate.
You can ship primed brass via UPS same way as shipping ammunition. You have to go to a UPS center (not store). Maybe you can trade those.
Sounds like a road trip is in order.
