Tight hold vs velocity

I read on another forum that if you have a tighter hold while shooting prone your velocity will be higher compared to a looser hold. The author actually did it with a chronograph. His results were indeed higher with a tighter hold !! This was with a 308 Win F TR rifle.

What are your thoughts on this?

Thanks again
 
I assume he means shouldering the butt vs. free recoil. That seems it could translate into increased velocity. How much difference was he talking about? Wondering if there were enough rounds of each to be statistically significant. Also depends upon the weight of the rig as a whole.
As a sling shooter it is a no brainer - we have to hold on. Seems the F-TR folks are split over holding hard or barely at all. Did he say how is long range accuracy was?
 
"I assume he means shouldering the butt vs. free recoil" Yes...that was part of it. This was done over a lot of bullets not just 10-30 but rather 1000's from what I recall. Not in one day but over a period of time with careful notes. Tighter hold was the winner in the end at long range (1000 yds). I think it was about 30 plus FPS with a tight hold. This was with a 308 F TR rifle. I can't find the thread now but it's on ozfclass.com , the fellow is one of the top shooters over there from reading other articles.

A top Army shooter told me to hold five pounds down and five pounds back and I did and it made my 800 meter group go from just inside the X ring to the size of a soft ball. Guess it works to listen to a top shooter?
 
IMO very few rifles, all of them special purpose, shoot their best with the least amount of hold that can be managed....yet many shooters continue to chase their accuracy goals using what, for their rifles, are the wrong methods. I see it all the time, fellows trying to shoot rifles that have field stocks as if they were benchrest rifles, from rests that would be insufficient for bench rifles, if they had one. Instead of experimenting with a variety of methods, they "try harder", encouraged by an occasional half decent group.

When I was first getting to know my 6PPC, after I had done the best that I could that day, tuning, shooting and reading wind flags, I would try different ways to shoot the rifle, a lot of different ways. What I learned is that with an accurate rifle, one can shoot it like a 7Mag deer rifle and if it is done by the rules (that one has to discover by trial and error) that very small groups can be produced. This knowledge came in handy on those occasions when conditions during a match would give some advantage to a shooter who could shoot fast, before the time when micro ports and ejectors were common. Being able to grab the rifle and shove it back on target, glance at the flags and squeeze the trigger four times in 20 seconds or less, before the condition changed was, in a few instances very helpful. The point of all of this is to encourage shooters to experiment, and experiment some more, with each rifle that you are trying to get the most from. You may be pleasantly surprised.

makes sense........... however accuracy trumps speed.............
 
We saw as much as 100 with a WSM with a pinned hard to stop verses Free recoil with slick bags and a 17 pound gun. Matt

Could someone please explain to me how a tighter hold on the gunstock can change the velocity of a bullet? Are we somehow altering internal ballistics? I can't wrap my head around this. I'm not necessarily sceptical, just dumbfounded.
 
And bolt head transfers the force to the locking lugs which transfers the force to the receiver which transfers the force to the recoil lug which transfers the force to the shooter.

My guns put the pressure on the bolt face . That's why I guessing I can shoot free recoil .

Simplstically: energy used to move the rifle backwards could have been used to move the bullet forward. Drew

Not hardly...

175 grain bullet @2600 fps = 65 pound-feet of momentum.
65 pound-feet of momentum divided by a 10 pound rifle = 6.5 fps
Bullet barrel time = ~ 1/1000 sec.
Rifle rearward travel while bullet is accelerating = 0.00652"
The shortening of the bullet travel by 0.00652" has NO effect on velocity - plus, the rifle recoils the same amount (durring bullet travel), whether you let it free, or shoulder restrain it.

Phooey on bogus science !!!
 
Not that one would do this but:
Rifle hanging by a string and fired vs a rifle with the butt against a wall and fired.
If all else were equal the one hanging by the string would fire a bullet with a measurable lower velocity?

And all that time the bullet is being pushed foward from pressure inside the the barrel .

OK, so it sounds like you would like to shoot better? Please give this some thought... Micro parts of a second is shorter in a shorter barrel then a longer one. The "time" it takes the bullet to travel is where you make or break a good shot vs a bad shot. Aside from matching the proper resident frequency of the bullet to the gun barrel, it also may help to consider your grip and follow through. ( about five pounds strait down and about five pounds strait back)
If you eliminate all of the variables theoretically the every bullet should go through the same hole. A ransom rest locks the gun down and should remove all but the ammo factor. That is why it seems better to first bench shoot to find the best load your gun likes before testing your shooting skills. It would be good to have a member test the NuFinish car polish to see if it shoots cleaner as well as faster.
 
I should have added that I would like to see the data to convince me that a hard hold did in fact increase observed velocity statistically significantly, and if it did, my simplistic explanation would be how I would explain it. Drew
 
It would seem to me that the proper thought experiment would be a sprinter coming of of his starting blocks. If two theoretically equal sprinters were paired ,and one had moveable starting blocks to push against ,he would get off to a slower start.
The bullet being the sprinter and the bolt face being the blocks, if the bolt face moves backwards at a greater speed, the bullet should leave slower.I would have guessed this to be negligible,but a consistent way of holding the gun makes sense.
