This is all starting to make sense now. I was even looking at some of my Cast Performance 440 gr. bullets that don't want to chamber in some of the Guide Guns that have tried them. This is another bullet that is made right at the ragged edge of what a Marlin chamber will or will not tolerate, depending on the condition of the reamer that was used to cut the chamber. I was looking at the Hornady brass and thinking about how it could solve that chambering problem, but I have only a few of those bullets left and don't have to bother. I am no fan of the LEVERevolution bullets in .45-70 and never suspected that Hornady would need to shorten the brass to make it work. Can I now conclude that ALL Hornady .45-70 brass is short, or just SOME of it? I have no interest in loading short brass.
