seafire2His formula was to fill a case until it overflowed...
Then level it off even with the rim of the cartridge, and then weigh the amount of Blue Dot for a full case...
20% of that figure is the recommended Minimum load...
30% is a good starting point to work up loads..
40% of that figure is a good point to proceed slower...
This is where it gets important....
50% of that figure should be in the neighborhood of Max, if the case is based on a 30/06 case....
work up slowly and in small increments above 50% of max in magnum cases, 308 and 7 x 57 based cases...
Max will be near 60% of full capacity in most cartridges depending upon bullet weight...( except 30/06 based cases.. IE.. 25/06, 270, 280, 30/06, 338/06, 35 Whelen)
Large Rifle primers are recommended, even in Magnum cases...
Blue Dot is not position sensitive in rifle cases, even with only 20% of max as a charge...
NO FILLER is recommended, as it will actually increase pressures....
Do NOT consider Blue Dot for maximizing velocity potential of a rifle case..
Consider it for accuracy and reduced velocity loads... at 40 to 50% you are not shooting reduced pressure loads.. just reduced velocity loads...
I am sure if you PM this seafire character, he will probably respond to your PM if you need specific info, or load data on a cartridge he has done load data for...
