@JAD:
Do you have a reference for the targets you mention-or images?
I agree on the VTAC and TLGs mentioned-they are quite useful and have variety of drills related to them. It’s almost a cliche, but the more variations of targets I can get the better. Steel i have found to be valuable in instruction/training, and can be utilized for testing(a la Rogers)-cost of course a concern. But even a 6-8 inch plate or two can “test” folks with a little forethought...or set a popper heavy, etc.
And of course, the good old B8...
