Anyone shooting 777 in an Encore 209X50 mag? I have been trying it and the powerbelts, and I have not had any luck with the powerbelts. I called thompson and they told me to try the shockwave bullets and they were a great help. I have been looking for a reliable source for information about the powder. I hear it is more powerful than the others on the market when used by volume. HELP
