I have a couple of thousand of the old CF "silver bullets" once fired and about a thousand that I have on hand already loaded up. They are, IMO, the best reloading Winchester hull I've found.
I have had quite a number of the first run of the newer HS hulls, with the AA in a box. I simply mark the base with a felt marker (and segregate them so they are not mixed in with later generations) to remind myself to check the barrel after firing. I just reload them once and drop them. So far, so good. I would not chance them in a semi or pump gun, but, as long as one remembers to check the barrel, they are okay to shoot.
I have a problem with the new hulls buckling when I crimp them after just a few reloads. I have hade them buckle even on the first crimp station. If it matters I have a Lee Load All but have never had any other type or brand of hull do this.
