What is seafire's formula for using Blue Dot in redusd loads. I keep reading start at 40% and stop at 60%. Percent of what? Is there a post that explanes it all? | ||

Well I know this seafire character pretty well... His 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...

Seafire2: Will that formula work for the .257 Wby Magnum. Was just wondering if it would be the same since that case is so large and the common powders used are the slower burning powders. Didn't know if Blue Dot would work in that situation. Thanks for your help in the past. Red C. Everything I say is fully substantiated by my own opinion. | |||

Red, PM answered.... I also like SR 4759 in magnum cases, like especially in the 25 to 35 grain range...that would bring the 257W down into the 250 Savage range...
