Reloading two 410 shells from one 12 Ga shell.

Is it possible to open a 12 Ga shell and then split the powder and shots and make two 410 shells?

You would only get one primer. Would be possible to weigh out the shot to get standard .410 3" weight of 3/4 ounce, if you started with 1 1/2 ounce 12 gauge. Or could get 2 x 1/2 ounce loads for 2 1/2" .410 if you started with one ounce 12 gauge. As I understand it, shot pellet size does not matter, but payload weight does matter. You would need 2 x .410 wads and 2 x .410 hulls. But you likely would have no idea what powder was used - if that was a commercial round, is probably custom made powder to produce that pressure and that velocity in that round - likely not a "canister" grade powder - so probably could not be used in a different round, without pressure being anywhere? If that was a hand loaded round, it probably did use a canister grade powder - if you know what it is, then can look up pressure tested data to know how much to use - for which primer, with which hull and with which wad. I have not loaded many shotgun shells - but I think that would be a really bad plan.
 
I think I remember reading about Russian boonies back in the day - they could get shotgun shells, but not rimfire shells. I think they cooked up a concoction to make new priming compound from wood strike anywhere matches - used the shotgun powder in the previously fired rimfire shells - I think the shot got melted to make the bullets used - three or four misfires were the norm, until the thing went "bang". I am not sure we are there yet, but was done at one time, in one place.

Powders for use in a 410 are different then what is used in a 12guage
Wads are obviously different too
The only components from a 12 guage shell that you can use in a 410 would be the primer and the shot
 
Solid advice from potash miner, if you're looking at maybe rolling your own ammo it can be a super rewarding hobby. There's a bit of a learning curve tho, important stuff to read into. Pretty serious consequences if done wrong but the information is out there.
 
I have 12 Ga 2 3/4'' shells with one ounce of #7 shots. Also have spent 410 3'' shells. I would cut them to 2 1/2'' prime them, fill with half of the powder, 1/2 ounce of shots and roll crimp them.
No resizing, using the same shotgun they've been shot from.
I hate to spend $35 on 410 shells. when I can buy 12 Ga shells for $13.

Fingers and eyes can't be replaced , use that grey matter between your ears, and listen to what you are being told. The 12 gauge powder is not suitable for the 410.

Ha ha, when I was 6 years old, living in the old country, we took a door key which was hollow and filled the hollow with scraped matches's heads.
Then we tied one end of a string to the ring of the key, the other end of the string to a big nail, shoved the nail in the hollow end of the key, grabbed the middle part of the string and hit with it a brick wall of the house. The sound was like a blind .22 cartridge ( 6mm Flobert).
