This is only my opinion: however, I would invest in a set of spring loaded snap caps.

Since used brass already has an indentation in the primer, it is not likely to cushion the impact of the firing pin the way a snap cap would. In fact, it might not cushion the blow of the firing pin at all.

As an alternative, someone on this forum has pointed out that you can punch out the primer in a spent cartridge, and then fill the primer pocket with a pencil erasure cut to size. I'm not sure of the effectiveness of this; however, at least one person has written that it works.

Of course you would have to do this with a spent cartridge that uses Boxer primers, rather than Berdan primers too.

My personal opinion is that for the amount of time and effort involved, it would be better to simply invest in the correct spring loaded snap caps.
