A friend I shoot with every week bought 5K of these recently and brought one to the range to show me.

It had no anvil, but the priming compound looked good.

I like to try things, so I got him to give it to me, I pulled the anvil from a spent primer, set it in the Bosnian primer and seated it in a 9MM case with a 115 grain RN Frontier bullet over 4.8 grains of Bullseye.

It went bang with gusto and the whole weekly group was clustered around me watching when I did it.

Did make the R.O. curious, so we explained the whole thing to him and he thought it was a pretty cute trick.
