I've been reloading them for several years, always use Cheddite 209. It has never been a problem with looseness, or anything else, in fact I assumed they were cheddites because of appearance and the fact they are euro hulls. I'm not pushing pressure at all, and mostly load 7/8 oz loads. I must tell you, that I have to use a 3/4 oz wad, because the base wad is set very deep as is typical of alot of euro wads , you need a wad with long leg length to get a decent crimp that is not concave. The 6 petal hulls last for quite awhile for me, they seem flimsy when you squeeze a spent hull, but I get at least 4-5 reload cycles before splitting at the crimp petals when they get crispy. Good luck, to you, definitely worth reloading unlike Fetters, Winny universals, super targets, super x. Challengers, RC itailians, are also like Bornaghi's and can be reloaded the same.
