If you know you have a good gun and bullets maybe it is time for a different hobby. I knew a drag racer that never won a race but he never gave up. A guy I shoot with has the best guns but there is no hope. He will hit your target aiming at his. He furnishes the gas and transportation to the gun shows so we have to be nice. My slap together ammo gets the same attention with good results. Head stamps do not matter. If you think they do go for it. You need good eyes and not shake and good lungs to be at the top of this.
