wadless loads?

[Haywire Haywood]

After much back and forth, arguing with myself like a nutjob off his meds, I think I have talked myself into a Bond Arms Snake Slayer 4.  Being the tinkerer that I am, I have looked into blowing out 9.3x74R brass for full length brass 410 shells.  Is there any real need for a wad in a load like this for a derringer?  Would a card on top of the powder and a card on top of the shot be sufficient?

Also, anyone have a powder suggestion for short short barrels.  No need for a slow powder that will just create a 3' fireball.  I've reloaded for pistol and revolver, but never for shotgun.  Edit... Duh..pistol and RIFLE.

i used 303 brit brass to make my 410's

The 303Brit looks like it will be limited to 2.5" cases, while the 9.3 will give you 3" magnum.  I thought that since shotgun case measurements are figured with the crimp open, a brass shell could be made for a finished measurement of 3" (or 2.93" in the case of the 9.3x74).  I've also seen where there's a wildcat 11.4x74R.  Someone came up with that to eliminate the bullet jump that results from shooting 45 colt in the 45/410 chambers.  Now I realize that in a derringer it's most likely wasted effort, but it would definitely draw attention at the range shoving what looks like an African big game cartridge into a derringer.  LOL

Actually their isn't much of a wad in a .410 to start with, and as for pellet distortion, that shouldnt even come into the picture at the ranges you'll be shooting, as to powder and pressures, that's a whole new game...........steg
