I think this is not true but I could be wrong. I always place my targets at the base of my berm. The targets are about 3 feet off the ground. A friend told me that's poor form because you are always aiming low when shooting. Am I missing something? Seems to me it would not matter? Dry fire seems to keep me on target regardless of target height. I bring up the front sight keep it on target. Seems to me target height should not be critical.
