I'm curious as to Claybuster 1118-12 wads. Aren't they a Winchester type wad ? Isn't a Winchester hull straight walled? IMR's 700-X has recipies for Remington STS/Nitros using them.......Is any of this correct? I guess my other question is : Should a tapered wad always be used in a tapered hull? And straight wad in straight walled hull?
