No. 172 Berdan Primers

I recently (hastily) picked up some #172 Berdan primers that I thought would work on .303 British milsurp fired cases. They are the correct diameter but about 20-30 thou too tall.

I have seen several sources on the net about what they were intended for including Dave Cushman’s site but I’m looking for info from someone who has used them and what cartridge/s they successfully used them on.
