NaphtaliHornady's 325-grain Flex Tip .458-inch bullet
The 2010
Gun Digest lists Hornady's 45/70 325-grain factory ammunition at slightly more than 2000 fps while the 450 Marlin factory load for the same bullet at more than 200 fps faster.
Since I own only Marlin 1895 rifles, a pertinent question is: Why?
Are there reloading data available from powder manufacturers showing reloads for this bullet in 45/70 brass that more closely approximate 450 data? If there are these data, please furnish link(s).

jeffeossolever/tubemag guns COULD have a strike the primer and blow up the gun issue.
450 and 45/70 are the same internal capacity .. and the 450 marlin is basically a 45/70 belted, loaded to marlin pressure (NOT 458 american 2" pressures - though its also the same capacity) .. the marlin is a hot loaded 45/70, every time, off the shelf ..

Excepting your information that 45/70 and 450 Marlin brass have approximately identical powder capacity, I don't understand [the remainder].

jeffeossothanks for asking..
the 45/70 can be loaded much hotter than trapdoor loads .. but most makers aren't really charged up with the legal ramifications ..
the 458 american 2" was the 458 winmag cut down to 2", which is roughly the same as the 45/70.
BUT .. you could chamber the 4582" in some of the belted, and WRONG BARREL HH based cases .. imagine a 458 bullet in a 300 weatherby!
enter the 450 marlin - with its taller belt .. and i think i touch wider ...
same capacity as the 45/70
loaded to the pressures a marlin can stand
BUT it can't be chambered in a trapdoor OR a 300 weatherby .. the bolt won't close
So you get hot loaded 45/70 ballistics in the same lever gun as a 45/70 .. and some of the same restrictions, as a pointy bullet in a tube mag fun could result in the bullet setting off the primer of the next case...
the 325 flextip give you a pointy bullet, that shouldn't be able to set off a primer
in effect, you get a pointy bullet equal to a hot loaded 45/70
make better sense?

Did you write that loading data for 450 Marlin (in 1895) can be used in 45/70 (in current Marlin 1895) for comparable results - with comparable pressure ranges?

Hornady's 325gr FTX data for the 45-70 Levergun exceeds the 450M data by 50fps.

in a word, no
