which bullet would travel the furthest

[krusty22.250]

I think this might be a stupid question but I'm asking it anyway? A buddy and myself have a side bet going and he thinks the furthest traveling bullet is the 22LR
So for example a 22LR bullet shot from a .22 would travel further then a 7mm rem mag?

[CoyoteChallenger]

i think the 7mm Rem Mag would take that one

uh, NOPE!

You win.

I hope you've got a LOT of money wagered on that bet Krusty. You're going to win ... hands down!

[davetree]

i guess you buddy never looked at a ballistics chart "dangerous up to x miles" easy money for you

[deanmc]

I have come across a few people that believe this. I wonder how it started?

[roger]

i dont even understand the question....


to acheive maximum range of any projectile, the bbl should be at or near 32.5 degrees(?) from the horizontal plane.

example...if both guns were fired at exactly the same time and at exactly the same angle to the earth. both bullets (7 and the 22)would touch the ground at the same time. the 7mm would just be further away.

another example...if you could shoot a gun parallel to the earths surface, and the exact moment the bullet leaves the bbl, you drop the gun..the bullet and the gun will touch the ground at the same time.
gravity is a constant..

I think for many of us it was the first gun we were allowed to take out on our own and we can still hear the lecture from our nervous fathers telling us how deadly a 22 can be. I think its qualities were exaggerated to make sure we got the point.

[Jester]

Years ago I bought some ammo that traveled thousands and thousands of miles.So the ammo that traveled the fartest for me was Sellier & Bellot from the Czech Republic...

But I tell ya...that cheap crap sure did fowl up your guns..

I do understand and agree with you in concept, but I would stipulate that the guns would have to be fired from level to both strike the earth at the same time. If both were shot at an upward angle, the superior velocity and BC of the 7mm Mag would give it an edge in the altitude it achieves; therefore it would be falling from a much greater height, and the .22lr would hit the ground first, gravity being equal. Fired downwards should be obvious.

G'day Roger!

You give two very good examples, but unfortunately they would only work in a pure vacuum (e.g. on the moon). As you say; "gravity is a constant" ... however 'air resistance' can be quite varied, depending on the size/shape/density of the two different falling objects.

For an example; Hold a feather in your left hand and a rifle in your right hand. Then let go of both of them at the same time. Your right big toe will be pounding with pain, long before the feather hits the ground.

And that would be my Science Lesson for the day.

[AndrewM]

The air resistance on a dropping bullet would be next to nil. The bullets would be in the air for the same length of time if they are shot on level ground at the same level. The only difference is that the velocity from the 7mm is faster so the bullet will travel further over the same length of time. Distance=Velocity*Time. The only variable here is Velocity.

Of course the bullet would need to leave the barrel perfectly level with the bore,which would be nearly impossible to do with the average rifle barrel due to barrel oscillations.Then you must consider that the fired bullet is rotating very quickly,and determine if that rotation will be a factor.Thirdly,the height that the bullets are dropped and fired from would be a factor.The higher the altitude,the greater the velocity,and the more effect that air resistance would have.The dropped bullet will likely tumble,while the fired bullet will probably maintain a stable path,will that be a factor?

[AndrewM]

The original question was which would go further a 22 or a 7mm. I am saying that all variables are kept equal at the location of the gun. Of course there will be an affect by resitance due to air but it is small in comparison to the velocity of the bullet.

JEEPERS GUYS!!
This reminds me EXACTLY what my old man used to tell me when I would ask a zillion questions about ballistics.
At times we get so wrapped up in "what if's " and YABUTS" that we forget the original intention of fireamrs or simplistic answers.
His answer was always " Shaddup and shoot, kid"!

[AndrewM]

Krusty, here is a website which will help explain it. http://www.worsleyschool.net/science...rajectory.html

[AndrewM]

I tried to explain it to my old man and he answered with the same thing! It is all quite "simple" physics. haha

[Grizzly Adams]

God, we must be getting Cabin Fever. So, let's change the question. If we fire both bullets straight up into the air, which one will hit the ground at a higher velocity?
Grizz

[krusty22.250]

So which bullet leaves the gun faster a 7mm mag of a .22LR?
Thanks for all the awsome feed back. Was just wondering which bullet would go father if two guys were shooting their guns at an endless gun range?

No Contest . . .

- 7mm Rem. Mag = ~ 3,000 fps
- .22LR = ~ 1,200 fps

Best comment made so far! I'm gettin' out o' this cabin and goin' for a walk. See y'all later.

Bye!

thanks andrew thats worded better than mine.
i should have pointed out that example one and two are not really related to the maximum trajectory statement.

Elk hunter,
Of course the bullet would need to leave the barrel perfectly level with the bore,which would be nearly impossible to do with the average rifle barrel due to barrel oscillations.Then you must consider that the fired bullet is rotating very quickly,and determine if that rotation will be a factor.Thirdly,the height that the bullets are dropped and fired from would be a factor.The higher the altitude,the greater the velocity,and the more effect that air resistance would have.The dropped bullet will likely tumble,while the fired bullet will probably maintain a stable path,will that be a factor?

nine point seven one meters per second squared says that everything falls at the rate, i beleive it converts to 135 mph.
ahh this take me back to engineering class (and thats not good)

now its a mass versus weight question, which is heavier...a pound of lead or pound of feathers??

[elkhunter11]

Actually it's 9.81 meters per second squared,and not everything falls at the same rate,unless they are in a vacuum.

i beleive it converts to 135 mph.

The terminal velocity varies with the particular object.

9.81 meters per second/per second is the acceleration of gravity. Ballistic co-efficient ("drag") is the main factor affecting the solution. Not everything falls at this speed, due to 'drag' but gravity affects everything equally, regardless of velocity, mass, density, etc.

Exactly my point.Contrary to what some people have stated,there are factors other than gravity that need to be considered.

i am no physics genius.....or a ballistics reader...but i have tried to shoot my 22lr 300 yards and it din;t get there..i know cause i saw the puff of dirt from where it hit...but i shot off the same rest on the same bench on the same day etc with a 7mm...and hit the target at 300yards...answers the question for me....but where am i missing the riddle??

[krusty22.250]

I thought it would have been an easy question to answer. But the cences I get is that the 7mm mag would travel alot futher then the 22LR when out hunting or shooting on any given day in Alberta.

[Cowtown guy]

Myth Busters was doing something similar to this about a month ago. They were trying to figure if a bullet would have enough energy to kill or maim someone if it was fired straight up into the air. Simple answer is probably not. They were able to take ABDUCKNUTS formula and find the resistance of the air and terminal velocity on a couple of different bullets. Very interesting experiment overall.

It should have been! We just got carried away ... sorry about that.

I'm going to blame it all on Roger ... he got us started!

Correct ... that would pretty much sum it up!
