My dad and I both load the not so premium hulls once, and toss em - i.e. Gun Clubs, Tops Guns, etc……and we will load the premium hulls 5-10 times, depending on how the hull holds up - Gold Medals, STS/Nitros, AA’s etc…once the crimp area starts cracking, they get tossed.Yep. Have been loading them for the past few weeks on a 9000H. The Cheddites seem to seat fine in AA hulls and ok enough in STS hulls. But with Gun Clubs - ugh! I’ve had so many problems with low seating primers - even on the second Cheddite reload - that I won’t use those components with that machine. Maybe it’s the steel bases and the shape of the primer pocket. Other than that Gun Club issue, they work great for me.
