Quoted: Please allow me to be the voice of uncertainity. >gg< Is that short a barrel capable of getting the 45/70 up to speed like it should be? Seems like a 20" minimum barrel, if not 22", would be a much much better for ballistics?

I could be very, very wrong about this...
If I read this right, on MarlinTalk, the .45-70 seems to be immune to velocity/energy level changes in the 18-22" bbl. length range, or, something to that effect.
I got 'weirded out' reading that. How could THAT be, I wondered.
I guess the comment was meant to mean that the .45-70 just isn't affected much by the length of bbl., kinda like if you get hit by a freight train, it doesn't matter how many cars are behind the engine, it's still a freight train!!!
OR, the .308 isn't affected much by the bbl. length being 20" or 26", until the range becomes extreme.
Something about these two calibers/cartridges is very weird indeed.
