It looks like Tampa, Zephyrhills, Pasco County and Pinellas County are ahead of the game.

They may be ahead with the classroom sessions but don't be surprised as some post may have been shooting semi's the past several years but just not at competitions. Be very very afraid of the unknown!

hmm what changes? sight picture, breathing, trigger. then bang, Either you can shoot or not. It does not matter semi or wheel gun. The last time I checked those posts shoot pretty good.
