Are you REALLY bored with being locked in the house ? Here's one cure. Truth be told I borrowed this from a gentleman named Larry Gibson on that other cast bullet website. Many want to shoot cast bullets in old rifles that only Berdan primed brass is to be found.
My situation is different. I bought 5000 rounds of RWS German mil-spec 7.62x51. Great ammo, beautiful annealed cases but fitted with a crimped in and lacquered in Berdan primer. Crimped and lacquered is a pain for normal reloading but facilitates the conversion.
Here are the steps: (fired cases ONLY)
1. Center punch the primer mark.
2. Drill through the primer and the Berdan anvil to form a new flash hole. I used a a 2.3 mm drill bit.
3, CAREFULLY drill through just the bottom of the cup with a #45 drill. You want to leave the sides of the cup and the Berdan anvil in place.
4. Take your primer pocket swaging tool (mine is RCBS) and swage the pocket with the SMALL punch.
5. You have swaged what's left of the old primer to form a small primer cup.
Now you can reload the case with regular dies using small rifle primers. As noted earlier have the Berdan primer both crimped and lacquered removes any concern abot the new "pocket" from coming loose.
Second to last pic shows a case ready to prime and one fired after conversion
I have lots of cases and free time !
