I reload Berdan cases already so I know how to go about it. Its just that decapping is a pain.
I see people converting cases to Boxer due to the limited availabiity of Berdan primers and then having to glue them in place to get them to stay seated. I don't know why when someone drills out the anvil they automatically think they have to use a boxer size primer.
Also when you reload berdan cases with berdan primers who says you have to use the original anvil?
By drilling out the anvil which a lot of people do so they can use boxer primers the decapping process is greatly simplified.
Combine these two schools of thought and you get berdan sized primers that don't leak with a boxer flash hole that is easy to decap.
True not everyone is going to want to drill a new flash hole, but for those willint to take the extra step and do so, they will be rewarded with much faster decapping on future relaods, and alot of guys already doing it would no longer have to glur their primers in place.
