30-30 200 GC with WC860 (Mil-Surplus) in Mossberg 464
Lee 308-200 GC LRN sized to .309"
2.5cc of WC860 Mil-Surplus Powder... DO NOT REDUCE, pressure is already low and powder is compressed into the case when the bullet is seated. ***Slow powders have been said to sometimes detonate in cases that are not filled***. If you do not see powder (2.5cc of WC860) reaching the base of the neck in your cartridge case, you are messing-up and may discover bad Voo-Doo when fired. Just don't mess around with the powder measurement.
PR: S&B LR
C.O.L. 2.685" (Already fired once in the same rifle, and "neck sized only" produces the best groups. Be sure to chamfer and size the neck tight before seating, or Boolits may creep back out of the neck. If the C.O.L. extends beyond 2.685" in my rifle... they may be difficult to cycle in and out of the chamber, if not jam-up altogether. This is a big Boolit for the 30-30 and may not work in other brands of lever action rifles.
Results: 1700 FPS, with groups of less than 1" at 50 Yards (iron sights), using a Mossberg 464 lever action with a 20" barrel. Some un-burned powder remains in the barrel and may roll out into the chamber and action during extraction of the spent cartridge. My rifle has no problems cycling despite traces of unburned powder during cycling.
Energy Formula: 200x1700x1700/450436=1283 FPE
