Saw a post here a while ago asking about factory loaded #7 shotshells....
Came across these on Cabelas. Sound interesting. Thinking about trying them on ptarmigan in AK this year...
Winchester White Wing SP Heavy Game Shotshells Per Box
As the white-wing dove population expands North from the Southwest brush country, hunters are facing a new challenge when it comes to bagging a limit of these high- and fast-flying birds. These special loads are Winchesters answer. They feature bigger payloads than standard heavy game loads for dense, hard-hitting long-range patterns, yet they keep recoil manageable for comfortable high-volume shooting. Loaded with No. 6, No. 8 and hard-to-find No. 7 shot, they are also ideal for grouse, chukar and quail. 25 rounds per box.
