357 Max comes along with 1680 in a wide range of bullet weights. The Legend accurate 1680 load data data about the Hodgdon web site lists only the Accurate 1680 180gr bullet. The max charge outlined is 27gr at about 31kpsi. The beginning charge is a good deal much less, and I wonder if it could even cycle an AR. So, you're yourself. Like Captain Kirk.
In truth, it was faster than any manufacturing unit load I analyzed. There was, however, a concern: The load would only feed about 50 percent of enough time. An adjustment in overall length might appropriate Accurate 1680 this problem.
Despite vertical stringing evident—a results of the supersonic/subsonic velocity blend—the 190-grain VLD load was a lot more accurate than any of your subsonic factory loads I tested.
