I never would have sought out this cartridge. A hot 45/70 can do anything the .450 Marlin can and I am a long time 45/70 fan. In a sense this round solved a problem that did not exist. However, I got a Marlin MXLR in a trade to even out a deal and it came with reloading dies and a ton of brass and factory ammo. I have grown to love the caliber and the rifle. With the right load it can shoot MOA all day long. This weekend I took it to the Pumpkin Blast IX shoot. I loaded up a 300 gr JHP bullet over 52 grains of Reloder 7. What a freakin' THUMPER. on both ends. This monster just destroyed pumpkins. It was chewing 8" - 10" chunks out of big pumpkins and exploding smaller ones. I do not think there was much there doing as much damage with a single shot. If someone was headed out to buy a big bore lever gun I would still recommend the 45/70 due to accessibility. But for a guy like me this is a great rifle as I always like to play around with oddball rounds.
