RE: Copies of A-Squares thinking?
I honestly have never heard of A-Square but I like what you have brought up. Essentially having three bullets that hit the same spot but do different things. One for varmint hunting that will make a PD pop like a balloon, another for hunting that will expand but not fragment too much, and another long range targetshooter. All could use the same powder charge and seating depths. Just pick the bullet for the required job of the day.
That would be nice!!
