THE TRUTH ABOUT BARREL MOVEMENT ???

[Bill Norris]

I guess Bryan has the facts concerning barrel movement that has long been argued especially by Eric Higgins on "Believe the Target" with Erik Cortina. Tim Sellars has also agreed the barrel does in fact move prior to the bullet exit point.

Videos Reveal Rifle Movement Before Bullets Exit Bore of Barrel « Daily Bulletin

This report is from Bryan Litz and the ScienceofAccuracy.com website. As long as there have been rifles, there has been a debate as to how much – if any – the rifle moves prior to the bullet exiting the bore.

Can't dispute "Newton's Laws of Motion" !!

I was actually surprised how little vertical barrel movement is seen, until the bullet exited the barrel. Especially when you take into consideration how much poi change occurs if you have the barrel against something solid (tree trunk, post ) left side pressure, right poi shift.

It's more than it looks but the important thing is, it's there and you see it. Love that but on stiffer br contours, it's still there, but you may not see it at this FPS video. You absolutely see it with better test equipment though.

What the “slo mo” does not show, is there sideways movement because of the barrel twist ?

Yes, there is a sideways moment, too. Not sure why anyone would question that if they'd actually shoot and test, though. But yes, I do buy that groups are typically biased vertically due to gravity. Nothing really else and the forces at play CAN be equal to the vertical forces but it's not common. No voodoo. No magic.

I will say that Bryan is onto something in terms of what happens regarding bullet flight after muzzle exit and that this is good stuff!

"barrel time" is a thing, ask a smallbore sling shooter, years ago my friend German Salazar started cutting his smallbore barrels shorter and shorter and found that a shorter barrel (less barrel time) made it a little easier

Who ever doubted it? How would you change how it shoots by moving the load if it didn't?

Eric Higgins on a pod-cast with Erik Cortina "Believe the Target" some time back was saying he did not think the barrel moved either before or after the bullet was fired. Yea I thought it was kind of crazy too.

Would that not be easy to test using something like a universal receiver and a non contact measuring device.

Because of barrel whip sometimes a higher charge weight the lower the point of impact. Speaks for itself.

Here is pic for example....

Absolutely seen it many times.

 

[Zero333]

Absolutely seen it many times.

Also, most people think the barrel whip is up and down, while the target certainly shows there is left to right harmonics at play as well.

 

[Bill Norris]

Seems like the barrel would move in all directions.

If anybody is gonna answer the question, it's these guys. They have their hands on a 2 million frame per second camera now. And they do videos on firearms.

If somebody @Forum Boss can get them to do a video on barrel movement then that would answer the debate once and for all

The harmonics associated with higher charge weights impacting lower on the target result in only a few thou muzzle movement, so that camera will need resolution as well as speed.

A higher muzzle velocity will also get the bullet out of the barrel quicker before recoil can lift the muzzle as much. Just ask a pistol shooter!

And why we used 452AA and a 200gr. HG-68 bullet. But still......When
you bust the cap, that barrel is moving. As I said in a previous post......
"You can't dispute Newton's laws of Motion" No matter what degree
of movement, it's still moving.....

5 or 6 years ago I came across a video in high-speed showing clearly the barrel whip. Might be still out there somewhere.

Probably a flat earther
