I'm going to sound like an idiot here. I don't think I've really ever gotten the proper double tap method down. I can throw 2 rounds fairly quickly into a target at close 7 yard range, but both are individually sighted. My thinking is that a double tap is where the first round is sighted and the next is aimed by recoil timing. i.e. the barrel returns from recoil and I instinctively pull the trigger again. Is that true? Also, how close should these 2 rounds be to each other at 7 yards? What is a reasonable expectation? How can I practice to improve speed and accuracy with this technique?
