Cut the case down as far as you can go. The case head has a thick spot behind it, you should cut down to that level. The amount behind the rim is unimportant.

Thank you

Nope, none at all.

j/k is internet for "just joking"

"38 spl lift kit ball bearing size."

One that fits down in the hole. You just want a small amount of the bearing surface sitting above the case.
Okay. Clearly I am not a ball bearing expert, but I assumed a person would want a ball bearing that would fit snug where the primer was removed. I guess I asked a stupid question. Those tend to yield similar answers. Clearly a ball bearing that is larger than the hole will not work. Am I incorrect that a ball bearing that is smaller than the hole will not work because it will move or even fall out. So I guess a more intelligent question would have been asking what size the hole is so that I can get a ball bearing to match. That would seem to avoid answers such as, "One that fits", or is there really no problem with using a ball bearing that is smaller than the hole?
