not a pansy .451/.452 handgun bullet
Actually the 460 is quite versatile. Visiting Hodgdon's site, we find that in pistols the 460 can push out a:
395gr hard cast pill at 1796fps giving a nice little 2829fpe! Ouch! That's not some wimpy pistol round there. There are also .452 jhp MAG bullets with thicker jackets to hold up to rifle type velocities without breaking up.
The 460 can also throw a 240 grain pill at 2184fps for 2707fpe not to shabby their either. I don't recommend shooting the 200 grain loads in the 460 same issues as with the 357 max.
300gr at 2067fps for 2845fpe.
Now for a couple of 45/70 pistol loads
The 45/70 throws a 405gr pill at 1445fps for 1870fpe (more in line with 454 casull loads)
A 385 at 1537fps for 2019fpe. Or a 300gr at 2076fps for 2870fpe almost exactly the same.
Now things might get interesting if you go to the 12 inch barrels or longer. But basically, the 45/70 can throw heavier lead, the 460 light flatter. A little more versatile for the loadings considering you can do the 454 casull or 45 colt for the light work.
The 45/70 works at much lower pressures while giving great performance. It it still a great round. I'm looking on getting one in a Marlin Cowboy, a BFR in the same would be a great match.
But of course as stated in other posts, "their ain't nothing like a 500!"
325gr at 2002fps for 2892fpe
370gr at 1949fps for 3120fpe
and loads up to 700+ grains of goodness coming at you.
All three loads are great. I'm only missing the 45/70 and that will be soon enough
