Got some half jacket 150gr and 146gr Hp's I'd like to use up. Any body got and data using Blue Dot?
I actually found some data in Ken Waters/Pet Loads. The one I was looking at was 10.0-11.3 I think I might just start at 10 and work up from there10gr-11gr is the range you need to fish in. The half jackets were problematic for leaving the jacket in the bore, the reason they were discontinued.
It's interesting that a 5% reduction in charge, nets about 10% loss of velocity, and a 20% drop in chamber pressures. A rough guideline culled from decades of Handloader Magazine.You can tell you are shooting a magnum load but it is not a snappy load.
