You would be surprised how many people just throw their guns on a prayer that it comes down the right way. It is poor technique. I start with a single, recognizing that the butt is verticle twice before the catch, a double the butt is verticle three times, triple....4 times, etc............ Really watch the rifle and understand it's every move in the air...... Be experimental also by throwing slow and lofty, fast and tight, throw a bad one on purpose, then throw a good one. I also throw half catches on purpose to train my self how to catch a "half" and not drop it. I do my "ladder" like this: single, single & 1/2, double, double & 1/2, triple, triple & 1/2, quad, quad and 1/2, five, five & 1/2, six, etc...... Then I do the ladder again with all fully rotated catches. Then again with all the catches on halfs. Then I mix them all up and tell myself random tosses and this trains your mind and muscles to recognize the process to make a solid catch. It's a work out for your brain, but takes the fear, anxiety, and guesswork out of tossing in your shows. You can also do the whole exercise off the right hand to. I know it sounds totally unconventional and useless...........but it makes a difference......... especially when the director needs a reliable soloist who doesn't drop.
