Why should one buy a new gun (Marlin 1895) in .45-70 if the potential of this cartridge can only be achieved with handloads or by buying very expensive special ammo i.e. Buffallo Bore or Garrett’s, if the same gun is available in .450 Marlin that can do all what a beefed up .45-70 can do, while the .450 Marlin is available without all the hassle, with better accuracy and without the risk of inadvertently stuffing an +P load into an old trapdoor rifle?

Umm......maybe because we ENJOY handloading and load development??

That's why I'm here anyway. If you find handloading to be a 'hassle' then you should buy a 450 and factory ammo and be done with it. But why are you here on Accurate Reloading?

As was stated by a Hornady engineer the 450Marlin is a 45-70 for shooters who don't reload.

that pretty much sums up what the 450marlin is all about.

If you reload get a 45-70. If you DON'T get a 450.

The ORIGINAL discussion, "Plan A", was with Hornady and Marlin going to SAAMI to create a "+P" standard for the 45-70l, that didn't work out.

The 450Marlin was "Plan B"

"Do you reload?"
whenever someone asks for advice in choosing between a 450 and a 45-70 that's the question I ask, it's the ONLY question I ask.

It is the ONLY question that is relevant to the difference between the two cartridges.

Will not work in a levergun Tom, bullets are too long. Hornady makes the 45 70 cases about a tenth of an inch shorter because leverevolution
bullets are longer from the crimp groove to the tip. That said I have never seen a 450 marlin cartridge though I suspect the same bullets are used in both the 45 70 and 450M.
You could cut off the rubber.
Whit Spurzon said this earlier and nobody noticed.

You could modify the Marlin to cycle rounds .1 inch longer.
