Rookhawk:

16's are not common anyway, so wherever "out there" is....there is probably not off the shelf 16 ammo available.....heck, most Walmarts don't even have 16's with any consistency.....

Pressures on even the low grade 16 Remington Target loads 2.75" (dove and quail as well) are too much for the old guns IMO............

Maybe you should just take an old 12 with you where ammo is more common........or a modern 12 for that matter and knock yourself out.......?..........

Lot's of folks do ship ammo ahead to their destination, but yes, they pay the hazmat fee.......just the way the 'new' world is...........and you live in one of the worst states for 2A stuff that exists..........

Good Luck,

Doug
