I got a Marlin 1895 in 450 Marlin/Hornaday in a trade. The cartridge is interesting. It has wide "Magnum" belt and the performance of a "hot" 45-70. The belt keeps you from a loading in a Trapdoor Springfield (or 458 Win Mag). It does nothing more than a Ruger #1 or Marlin 1895 45-70 loading (or handloading) but it was Lawyer safe. Not a fun rifle to shoot, but if you had to hang out in Brown Bear country it would be a nice thing to have. Getting ammo could be tough (as could be +P 45-70), but since it kicked so hard, a couple of boxes should be plenty. The flex-tip bullets get you a bit more range, so a 200 yard rifle with the 325 grain was certainly possible. As said above, not a range rifle but as a big game taker, it would have been plenty. I traded it to a guy that loved lever actions.
