I will be surprised to see ammo for this offered in another couple of years. Seems that Garrett and Corbon began offering 45-70 loadings tht were the equivilent of the reloading manuals "Lever Action" or "Class 2 Action" pressure level loadings. Within what, a year or so maybe 18 months, Marlin created and marketed the 450 Marlin. A lot has been written and speculated on as to the offering of this round. In short, it is a Class 2 level loading of a 458 caliber bullet, in a case with almost identical volume to the 45-70, with a larger diameter belt to prevent it from being chambered in something like a 300 Win Mag or a 375 H&H. The bottom line is that it is a hopped up 45-70 in a modern case design. It is more powerful than the ammo oferings form Winchester, Remington or Federal, who continue to load 45-70 ammo as though it may be used in a Trapdoor Springfeild. Overall, the cartridge has been met with all the warmth one would give a damp mop. Those who were reloading the 45-70 hotter than factory ammo, continued to do so. Those who were shooting the 45-70 only with factory ammo, continued to do so. A few, perhaps like yourself, who wanted to buy something warmer than factory 45-70 offered, bought the 450. Some I am sure bought it because it was something new. The nice thing in your favor is that it uses the same bullets as the 45-70, so there will never be a shortage. I would, in your place, either buy up an extra box of ammo every chance I got, or begin reloading and buy an extra 50 cases or so every chance I got, as the belt being larger than the belt on an H&H derived case leaves out the possibility of making brass from 458 Winchester or similar. It will be interesting to see how long Marlin offers the chambering.......
