Had to test it out. Results were a 20 foot or less effective range. Does have a 16 inch halo at 20 feet, but some chance of hitting grouse in center potion, especally with wad. Used 2 1/2 inch .410 shells #6 shot, with 1/2 inch brass head. The brass cracked in two or three places, but the plastic held. No visible gas escaped, plastic body looks like it expanded to chamber.
After 4 shots the bore had a deposit of grainey black unburned powder. Think I would like to pull a patch through before shooting a regular round.
Warning do not try this with 3 inch.410 shells. they will probably stick in barrel if cambered and probably have a real constriction when the crimp opens up in the riflings. As it is the 2 1/2 inch has a half inch of crimp past the chamber.
The rim is smaller than the 45/70, and the ejecter just grabs it. Works best if your Marlin has the port facing down.
Checked out my old roundball grouse loads at same time. 143 grain pure lead round ball seated over 5 grains of 230P with corn meal filler, CCI 200. Velocity around 830 FPS. With iron sights set @ 100 yds for 350 Gr @ 1825 FPS , the impact is 1 1/2 " high at 20 feet, 3 1/2 high @ 30 feet, and 6" high at 25 yards. Makes it difficult to remember where to hold for sporatic use.

Greetings from California, where we are putting on a Seminar on our Military Gear.

If you want to greatly increase the range of a .410 load from any 45/70 you can thread an old-time T/C 45/410 choke onto the end of your barrel. It'll tighten the pattern--make a real shotgun of it. I've done it on .44 mag and .44 Special handgun too (using Speer shotshell capsules).
