The bullet does not leave the barrel before recoil...

super slomo vid shows the recoil moves the barrel before the bullet exits the barrel highlighting the importance of proper shooting position over barrel harmonics.

Recoil starts when the bullet starts.

Yep that whole equal and opposite reaction thing we learned in school. Can't get away from it.

I wonder how much more/less pronounced that becomes with changes in velocity?

lighter calibers are easier to control recoil than heavier calibers...

A while back I was reading somewhere about how its preferred to grip the forearm instead of using the cross arm hold when shooting heavier calibers. The straight back recoil in the slo mo video seems to validate that.

Over the years, I've heard about the importance of what is called, "follow-through."

A while back I was reading somewhere about how its preferred to grip the forearm instead of using the cross arm hold when shooting heavier calibers. The straight back recoil in the slo mo video seems to validate that.

Stock design influences felt recoil. Things like drop at the butt, curvature of the grip, etc. I have Rugers and a Winchester with near straight back butt stocks; that design seems to deal with recoil more humanely than others. Like another Winchester I have with a Monte Carlo stock, that one beats me up. Shooting stance and physique supposedly should be factored in with stock design, but not many of us can afford custom designed and made stocks.

When shooting heavier centerfires, I always hang onto the fore end; I will use any additional purchase I can get to keep from getting beat up.

Maybe? My 7mm magnum hits at 1300 just fine with a cross arm hold. I find it more comfortable.


I was thinking more in the velocity extremes such as a .45 ACP at less than 1k ft/sec from a rifle and a .204 Ruger at 4k ish and when/how far the barrel moves though those two aren't exactly apples to apples

I experimented with the forarm and cross arm hold and undecided but lean to the cross arm. My 280ai is comarable to a 7RM and Ive never thought either of those "lightweight" calibers so maybe what I read a while ago had to do with even larger magnums like the 300WM.

I would think a hyper fast velocity rifle would have less chance of user input affecting the accuracy, but by how much I dont know.

I wonder how my stock is hindering my accuracy, its a factory rem 700 about 30 years old, classic hunting walnut monte carlo I think. I dont want to replace it as its a classic and beautiful. I find that comfort is my best shooting position, typically sitting at a bench rest, as long as my position is comfortable where I could hold it a long time without fatigue I shoot well, but I also know the cheek weld is important. I can see how a modern adjustable chassis stock would be the best, but those arent so attractive to me.

Get one of those coats with a big, built-in pad on the shoulder.

Last weekend it held .6moa for me. But Ive thought about adding a pad for a better cheek weld if needed.

Video is inconclusive. How do we know the shooter didn't jerk the trigger? I'm not convinced.

Bench shooting with a lighter rifle (this would include almost all standard-weight hunting rifles) is often better with "hard hold" on the bags (idle arm pulling the gun down into the bags at the area of the recoil lug).

Varmint and target-weight guns generally do best with the conventional "cross-arm" hold, idle arm remaining idle.

No gun sighted at the bench is necessarily sighted for hunting/field shooting positions.

This is so very true.
It is wise to practice hunting and field shooting positions / conditions with your hunting rifle.

The bullet does not leave the barrel before recoil.... Begins.
Once the bullet starts moving forward, recoil begins, but it does not end until the bullet and the powder gasses (ejecta) do leave the barrel.
It all happens very fast, but it is not an instant thing. Just like the time between pulling the trigger, hammer/firing pin fall and primer ignition is not instantaneous.

But the murderbum leaves the traffic barrel before sundown. Important distinction.

Interesting but seems to me this is telling us minute detail about something that we all already know: if the gun is moving when the shot goes off, you will miss the target. You can move gun by trigger, unsteady hold, whatever it doesn't matter. So the more steady your hold is when the shot goes off the more accurate you will be.

There was a prominent airgun writer who championed "the artillery hold" for spring powered rifles. He said hold rifle loosely and let the gun do what it wants and it will be more accurate. I tested it extensively and he was full of bubblegum.

Springers have both forward and backward recoil from the spring mechanism. Letting it doing what it wants means the gun is moving a lot when the shot goes off. Holding it as steady as possible, just like any other rifle, gives much better and more consistent results. Airguns may need more "follow through" time due to lack of speed of the pellet or delay between pulling trigger and pellet leaving the barrel.

Actually it's the same with DSLR cameras. You push the shutter button, a mirror flips out of the way, a shutter opens then closes, and mirror flips back down all in 1000s of a second. If you don't hold the camera steady (including the "follow through") you will introduce blur (which can be seen as lack of sharpness) to the photo.

It's almost as if "prominent" doesn't automatically mean "helpful".
