I inside sharpen the end of a ctg. case, and rotating the case between my fingers, cut multiple disks at a time, against a HDPE or UHMW cutting board. The poly board doesn't hurt the case and works well.

I will be trying the vegetable wads (trackofthewolf) in my Sharps this coming summer to see it they work for me with a grooved lubed bullet.

Paul Mathews initially wrote about the wax paper, then switched to Bee Brood Foundation beeswax available from bee keeper wholesalers. I've not tried it as the wax paper worked well for me and takes up litteraly no space in the case.

You can put any number of requisite wads between the lube ball and the bullet, just as long as the lube ball is disintegrated by the flame - Pauls explanation on the process - sounds about right and worked for me.
