maybe someone can answer this,
i have a 44 mag pistol and a 44-40 rifle.
ammo looks the same, are they?

 

[duckman76]

They are different rounds. The 44-40 meant .44 caliber and 40 grains of black powder. New loads in the 44-40 use modern powder but that is just where it came from. The .44 mag is a little shorter and not a rimed cartridge. They are not compatible with each other.

thanks duck for info.
my dad passed away last year and ive never had these guns before .
i just started looking at them and seen the simularities.
very interesting!

44 mag is rimmed

 

[BrownDawg]

what do you mean by rimmed?
both shells have primers.
both shells are the same length

 

[fjp110]

they are not the same. do not try to interchange.

 

[duckman76]

No they are not the same length. The .44 mag case length is 1.285 and the 44-40 is 1.305. By a rimmed cartridge I mean that the 44-40 does not have a groove after the rim. It is straight walled where as the 44 mag has a cut groove for the extractor. They are not innerchangable!

44-40 Win uses a .427 or .428 bullet and runs at about 10,000 psi 44 Rem mag uses .429 or.430 and is I believe around the mid 30,000's on pressure.

44-40 brass is also .020 longer than the Mag and tapers .026 from the head to the mouth.

As has already been said, don't do it!
