[QUOTE="Veteran, post: 2443895, member: 118038"] Per the Quick Load users manual. Its the percent of powder instantly combusted in the chamber vs. the percent that combusts behind the bullet as it moves down the bbl. and is the amount of energy lost due to bbl friction with the bullet, energy loss as heat, and energy loss due to gas blow by which gets in front of the bullet. If you are using Bergers set back .13 jump, in an old rifle w worn out lands, and using dense pack stick powder like N570 with 95% case fill, maybe this factor is 55 or 60% im QL? Thats my understanding from the definition below. Weighing factor: # Input, represents energy losses from friction, heating and gas leakage; (Default is an estimated value based upon consideration of various cartridge parameters.) Most data records contain a 0.5. This means that 50% of the propellant mass is considered to move with the bullet. For typical cartridges, this is a good figure with which to work, so long as nothing better is available. Refer to the associated Bubble-help (tool tip) window for more information. Wh [/QUOTE]
