Those are probably ok (I've never shot 'em), but I will point out that the muzzle velocity listed on those is quite a bit higher (1200 v. 980).

I don't remember exactly where I read it, but there was a bunch of skeet shooters griping about the Winchester loads noted above because they were so slow that they had trouble adjusting their lead on the target birds.
In the circumstances that we shoot CAS, I found that to be a "plus"

Looks like Cheaper Than Dirt and Midway are either out or don't sell these shells. I did find them at Gander Mtn online and Bass Pro Shops:

I normally buy them at my local Academy, Wal-Mart or Gander off the shelf for $7.50-8.50/box.
