I got started into firearms by fantasizing about a Red Dawn scenario and zombie apocalypse; with that in mind I bought mostly tacticool stuff. That got old relatively quick. There were no goals for me to pursue but wait for theTEOTWAWKI.
So I took up an offer from a former Marine and shot a match at Puuloa. Met a lot of very experienced shooters and learned a lot - still learning. While there is always a debate over traditional highpower, bullseye type shooting versus "tactical" type shooting i.e. Magpul vids, emphasis on reloads, weak side transitions etc. -- you can't discount the emphasis on fundamentals. Build a foundation on solid marksmanship then move on to tactical shooting if you want to be an effective zombie killer or space shuttle door gunner. I met two types of shooters: those that talk fundamentals and those that practice it religiously. That means understanding shot calls, front sight focus, trigger control, natural point of aim, understanding the environment you are shooting in: wind and light etc... It's easier said than done.
The most important thing is that you are truthful to yourself. Don't make excuses for your shots. Find the problem fix it, drop a round in the chamber and take the next shot.
