[QUOTE="su37, post: 287556, member: 5541"] "So I guess all those fireballs I see from my 458 socom weren't really there!! because all the powder burn't 18" back towards the chamber! RR" And to quote John Barsness again, "Actually the ball of flame is the hot gas from the powder reigniting when it hits the oxygen of the atmosphere, not still-burning powder. Almost all the smokeless powder in a charge, say 99% plus, is consumed within at most a few inches of the case mouth, and often a lot sooner. Of course the load has to create about the right pressure for the powder, as various powders are designed to burn best at different pressures. When the pressure is low for the powder--as in your Varget .45-70 load--then many powder granules simply won't burn. A few stay in the bore, but most are blown out the muzzle--but they aren't burning." [/QUOTE]
