The 1st question is what gun are you shooting the 444 in? If it is a lever, you may need to use other brass.. If it is a single shot it is not a problem. If you want to get rid of the used short brass pm me and we will talk. If you just stay away from max loads, you should have no problem. The 444 is a slightly tapered case, not like a severely necked down cartridge like say a 223 WSSM, so the pressure jumps are not nearly as great or as critical.
