[QUOTE="Trnelson, post: 1227930, member: 42308"] LC brass is thick, around 175g. It works reliably in my CETME without any of the extraction issues I routinely get using most commercial spec brass. As opposed to commercial brass that is specified in reloading manuals that run as light as 160g your LC has less volume available due to thicker, tougher construction. I reduce the powder charge by 10 -12% and see similar velocity. A good chronograph will help you figure out what is safe. Velocity is a function of pressure. I haven't played with R-17 in my rifle so I can't tell you how to start, but I can tell you that 43.0g of IMR 4166 pushes a 150g Hornady SST to 2,700fps in my rifle according to my magnetospeed.
