Which rifle bullet Goes the Farthest?

So far, I'd still have to say that the 338LM AI has my vote purely because it's packable and components aren't that big an issue which has been mentioned already. I'm with Mystic on this one. I've seen chunks of rock thrown up in the air by my 338LM AI at a mile which is impressive as hell but to accurately shoot 3kms, you might as well be putting up big $$ for a 30mm Laidi which a certain someone I know just happens to be reactivating a couple of.
 
I'm having fun with a good ol' 6BR at 1000 and out to a mile... It is a round that still continues to impress me after all these years.
 
just want to ask something the BARRETT is prohibbited by name and by the bullet so all BARRETT stuff is prohibbited? or only a few things are

As above, BC is very important. Weight of a bullet depends on what you want to do when you get out a couple of KM. If it is just targets, then bullet weight is not important since you don't need the retained energy.

As I recall there is a 50 cal bullet (BMG) that literally falls out of the sky as soon as velocity drops off at around 1000m. This is done with the design of the bullet that becomes unstable below a certain velocity, tumbles and looses velocity very fast.

The 50 BMG dose not fall out of the sky at 1000m....In fact it hits almost like a 460 Wby at that range! The longest sniper kill in history (2430 metres) was made by a 50 bmg....A Canadian no less!

Most bullets (not all) loose any semblance of accuracy as soon as they slow to sub-sonic velocities.
With standard match bullets (SMK) this happens at around 1500 yards with the fastest 30 cal mags. With the bullets Mystic mentioned I am aware of at least one fellow using a 408/338 CT that is shooting accurate groups (MOA)out to right around 3000 yds.

This fellow said that by moving the target back just another 50 yards the bullet would go sub-sonic and accuracy would immediately disappear......


Interesting No??!!!
 
I have seen this event where a bullet seemingly hits the 'wall'. A little closer, pounds the target. A bit further out (100yds or so), all over the map.

In talking to those that shoot extreme distances all the time, the main issue is twist rate. If spin/gyroscopic stability can be maintained through the sound barrier, the bullet will stay stable until it hits the earth. Some are using faster then normal twist and having success with bullets that would otherwise crash.

We know the 22LR can be shot to relatively extreme distances with no issue. Same goes for blackpowder cartridges. A balance must be met between the shape/stability of the bullet and the rate at which it is spun. Initially velocity really doesn't matter at these types of distances.

Everything goes subsonic.

Will test a few bullets and see if they can make the trip.

I am familiar with 50BMG ballistics. I was just demonstrating what can be done by playing with aerodynamics and developing specialized bullets. Range can be both extended or shortened.

There was a very special bullet made for the 50 BMG that intentionally would upset at around 800 to 1000 yards and literally "fall out of the sky" within a few hundred yards because the bullet starting to tumble severely. It was designed for ranges where they don't have miles and miles of safe area downrange.

I was going to buy a bunch of them about 2 years ago to shoot on our farm, north of Toronto because we only have about 1 to 2 km downrange. Now I can't find the store that had them.
 
There are formulas and software which analyze and determine bullet instability and some of the inupts are Axial moment of inertia(1X), Transverse moment of inertia(1y) and Centre of gravity(1cg). EBV4 and PRODAS can do this, but is difficult to use unless you are a ballistician/engineer(not me!), but at least I know I'm not. Did talk to one today, though. Interesting projects on the horizon.

Jerry,

Hitting a target at 3500 yards is pretty leading edge stuff....This sort of thing fascinates me!

Everything becomes a 45/70 at some point...I guess the trick is in getting a Vld bullet's subsonic transition to be smooth enough as to not cause instability....

The other issue must be establishing predictable trajectory tables....The instant the bullet goes subsonic all normal bets are off (with ingals type calculators)....How do they do that aside from live testing??.....I suspect they don't, but it shouldn't be too hard to create some sort of load specific drop profile (there might be a standard curve)that takes effect as soon as the bullet goes S.S.....Cool!

What sort of twist rates are they running in the 33's?

Do the extreme range guys have a web site?

Thanks!
 
Just go with a M777 155mm Howitzer
Maximum range 22,400 m (14 miles) with conventional ammo; 30,000 m (18.6 miles) with rocket propelled. Its crazy like that. Your couch is da bomb Doug!

Going to start with a 308Win for now and see how far it will go and then move up. A Tikka T3 Tactical will do the job? Now a high tech scope
 
Radical,
M777 hits 18-19km with standard ammo (depending on Met), 22 Km with RAP (Rocket Assisted Projectiles) and 40 km with Excalibur (XM193) GPS guided munitions...
