Not yet. You're breaking new ground........ I just chop 'em off with the trimmer and the stub almost falls out. Some times does. Use a straight pin if it doesn't.
Why not just shoot 'em w/o trying point the tip. bc will be way down but it wasn't much to begin with, and will be consistent. Plus it would be in closer compliance with the intent of the rule, it there is a decent intent. Heck, even with that little bullet you should be able to short half way across that narrow state.
The trimmer is nothing more than a 4 flute end mill. I'm thinking a Wilson trimmer would work if used after the cartridge was loaded. Look at the Wilson trimmer and be sure the flute go to the center sufficiently to trim the meplat. It won't on mine thus the Kevin Cram solution.
