What nose punch for Big Lube Boolits?

[August]

What number nose punch is recommended for RCBS lubriciser when working on 38=40 big lube boolits?  They have a large meplate, so I'm guessing something with a flat end would work real well.  Right now, I'm pushin' 'em in with a piece of sheetmetal between the punch and the boolit, then I've filled the punch I have with hot glue.  It's workin', but it's slow.

Thanks!!

     I just chucked mine in a drill and turned it off flat,with a file.No more deformed noses or rings on the noses. I cast mine of 70% ww s and 30% pure lead,so they are on the soft side.     Adios  Sgt. Jake

I asked DD about nose punch several weeks ago and he recommended flattening an unused punch.

Thanks, you guys.

I am continually amazed that great solutions are so elusive to my feeble mind.  Grinder on....

I dont know what number mine is for my Lyman, but it is flat with a small hole in the center. It leaves just a small bump on the end that is handy for identifying MY bullets. I always seem to end up with someone else bullet after a match, and I wont shoot em if they arent something I loaded.
