Try puting a crimp on the end of the case.
Well, that was simple enough.

Thanks.I used a rubber hammer and my lee loader to crimp six of these, and I shot them this morning. They seem to be holding together good. Now I guess I will order my dies to make this a hammer free process. I have enough Herco powder and 7 1/2 shot to make a couplea lifetimes of these. For about 2 boxes of .410 shells I can get the dies.
Here is my perfect snake load for the bonds derringer.
