winchester model 36 9mm shotgun centerfire conversion

[danyboy]

Anyone with experience in converting a 9mm shotgun model 36 winchester from rimfire to centerfire ?

What do you plan to use for ammunition?

No idea but I thought that if I could convert it to centerfire it would be easier to reload and I could probably cast some bullets instead of using it with lead shots. I know it wouldn't be much of a long range gun but it might be a fun project even if it just for target shooting.
I have no experience in shotshell reloading, just centerfire cartridges.
The only ammo i have seen for it is Fiocci loaded with lead shots about half the amount of a 410 shell wich isn't much.
Do you reload ammo for this gun ?
Have any idea ?
