I received this reply the other day and thought I might share it...
Ballistic Bridge Subbase & Flat Base Conical --------------------------------------------------------------------------------
Tried this idea of Ballistic Bridge Sub base with Flat Base Conical today. It worked great.
Without any wad, got groups over 3". With a 1/8" felt wad, things tightened to about 2". With the BBSB, produced two groups, each less than 1".
I never would have tried this without seeing this thread. It seems to be the solution for one TC QLA.

This was in response to another thread that I had posted...
