Calculating rifle movement as bullet reaches muzzle

[dmoran]

Are you saying that recoil is considered part of "internal or external ballistics"?

Internal is everything that happens between ignition and the bullet leaving the muzzle.

External is everything the bullet does AFTER it leaves the muzzle.

Recoil is....well...recoil. It has nothing to do with either.

But I do agree.....it has EVERTHING to do with precision shooting...even with machine rests.

In-bore bullet travel, recoil energy, recoil velocity, and many other aspects, are indeed aspects/part of internal ballistic calculations.

An exact measurement isn’t needed.

Nuff said!
Though, I will add, given the extent of investment in energy you’ve put forth in this thread, you might consider becoming a Gold member.

Always remember the old adage that there are only a few things that will cause a bullet to take the exact same path to the target as the one before, but an astronomical number that will cause it not too.

Jackie, that’s one of the best quick summations of the many mysterious (to some at times) quirk's involved in the pursuit of consistent accuracy.

Who is the shooting world isn‘t curious about how far a rifle can recoil before the bullet exits? If a rifle only moves 1/32”, that’s much different from one that moves 1/4”. Even as a teenager I’ve wondered this.

That's why determining the best setup for a bench rest, bipod, etc and the proper hold ( free recoil, hard hold, etc) are important for accuracy in order to manage recoil before the bullet leaves the barrel. The amount of pure backwards movement is only one of many factors in this total complex system, and not as important for accuracy as the factors not parallel to the bore which drive the bullet away from the point of aim.
