I guess I'm on Homer Powley's page, not yours.
I've played with Powley's load calculator. I've also looked around trying to find information that supports your quotes. Please point me to information where Mr. Powley says that all the powder is burnt by the time the bullet has moved 2" or so. I was unable to find it in my searches.
I'm having a little difficulty understanding your position. So, please clarify your opinion on this matter. Which of the following statements best describes your stance?
#1 Powder keeps burning as the bullet moves down the barrel.
#2 All the powder is burnt by the time the bullet moves 2" or so down the barrel.
