You are correct. I mean't to say hollow based.

You would NOT use a wad on a ball-et. I use them on the flat based R.E.A.L. conicals and the T/C maxiballs but not on ball-et and there were some other hollow based conicals that I did not use them on. For instance on my minnies, I fill them with lube but being hollow based they do not get a wad. The skirting on most hollow based conicals need to expand a little to engage the rifling in some cases....

As for the lube on the Ball-et it is real sticky and stays in place. I have hunted with ball-et and shot lots of them because my Hawkins Flintlock really likes them. They will not contaminate the powder. I just wish I could figure out what kind of lube that is. I'd make some at home and try it on my REALs....
