In an effort to get a better understanding of internal ballistics I'd like to know where exactly does the pressure peak. In the nanoseconds after the firing pin strikes the primer I understand that the primer ignites the powder and as the powder burns pressure rises in the case until the bullet starts to move. Pressure then drops until the bullet hits the lands and stops(assuming bullet is seated off the lands). Follwed by more pressure buildup until the bullet starts to travel down the barrel.
So which is it, in the case before the bullet moves or when the bullet hits the lands or is it at some point as the bullet travels down the barrel? How would/does this change if you seat into the lands?
Thanks for any input
