I load a lot of" one and done" loads. I don't like saving hulls unless they are premium hulls like STS. I have loaded a lot of the hulls from the Walmart 4 packs. These hulls are the same hull as the Federal "Top Guns" and have a paper base wad. They take regular American 209 size primer and I load them with either the 1 oz. "Lightning " wad or the CB 1 oz. 12SO clone. Sadly they are being replaced with a new 4 pack made in France. The new Wally World 4 packs from Federal are a completely DIFFERENT animal. They are the "Euro" design, have a plastic base wad, and if you load them with regular American wads you will get several SOFT loads and may encounter "bloopers". They have a bigger inside diameter and if you do load them you will need a wad designed for them such as the CB 610012 wads. Also a regular size 209 primer will fall out of them. They need to be loaded with an oversize primer such as Nobel Sport or Fiocchi. Just wanted people to know before they try and reload them.
