My dies are set up so if the meplat is the same size like these slugs the hollow point cavity will be the same so all the 17 cal no matter the weight will have the exact same size cavity. Same with all the dies regardless of weight or caliber, it the meplat is the same size the HP cavity is likely to be identical because we use the same tooling for the HP nose. There is a ratio between the length of the HP pin and width of the base of it so they don't break.
