I tried about 2/3 can of Shockey's Gold. Very inconsistent, there was noticeable difference from shot to shot. Could even hear the difference in report from shot to shot. Seemed to work best if I really crammed the sabot/bullet down on the powder. My own personal theory is that the inconsistent granules are the problem. Its more like pea gravel than powder. I then discovered BH209, and have not looked back. Gave away the rest of the Shockeys Gold. BH209 burns much cleaner, more consistent,and better energy. In my guns, the follow up shots seem to get easier to load with each firing. Just my experience.
