Hornady makes some of their brass shorter to work with their longer 'LeveRevolution' bullets. It would be nice if they mentioned it when describing their brass but ....I bought some Hornady brass 45-70. They were approx. 1/8 inch shorter than Starline brass.
So far I have learned that their 45-70 is short and their .348 Win & .32 Win Special are 'normal'. I have not heard mention of this carrying over into their handgun brass ammo but they do make some of that with the 'soft' tipped, longer bullets so it could happen.
