Until my MRP comes in, I went a head and bit the bullet and ordered two pounds of Ramshot Magnum. reasons, 1. It is a double based spherical powder that is coated so it is not temp sensitive and should give not only 15 - 20% longer barrel life than extruded powders, but since it is not temp sensitive it will not have as much Dev as other spherical powders do - therefore being consistent in accuracy like extruded powders. 2. It is at the top of the velocity chart with Quick Load program for a 180gr TSX. 3. It is a very clean burning powder. 4. It will be easier to use as a compressed load than extruded powder. I sure hope it is as accurate as some say it is. One thing for sure I will find out pretty soon.
