My friends at RST Shells are loading flyer loads in at least three different velocity ratings in 1 1/4 ounce lead. Go to rstshells.com for details and prices. They will ship right to your house. I shoot the shells and they are wonderful. They are not shy about the use to which these shells will be put. There is a picture of a pigeon on the box.
Don- No issues shipping shells, just have to go UPS or Fedex (Fedex is cheaper for me @ rack rate, UPS might be cheaper for you w/ a corporate acct), just has to be sent w/ an orm-d sticker (download from google pictures and print and tape) and adult signature requirement. I send my ammo for the World shoot in San Antonio this way back in Oct, Fedex, w/ no issues, cost me IIRC around 30-40 bucks for 60lbs worth.
Direct shipping from the RST factory to your home. They have daily pickup. No fuss, no muss. The available velocity of the RST Pigeon Loads: 1250, 1300, 1350. The nominal velocity of pigeon loads from the big three used to be 1225. 1 1/4 ounce high velocity loads were nominally 1330.
