For those who don't live in Oregon, Del may be willing to ship shot using Priority Mail. The limit I believe is 75 pounds and postage for a box for 3 bags of shot is something like $15 if I remember correctly.
I have been off the computer for a couple of days. USPO still ships up to 70 lbs in their flat rate boxes. That would mean 2 bags per box or 50 lbs. Cost used to be $10.35 but may have gone up a little. Del
