Does a bullet get longer...

[Owen]

bullets usually get shorter, from the nose being set-back. The material in the rifling is very small compared to the volume of the bullet.

Barnes solved the problem with the "Triple Shock" bullet, which has bore diameter grooves, allowing the displaced metal a place to accumulate.

My understanding is that the primary purpose of the TSX was to reduce friction. There is a completely different set of loading data for the regular X bullet, since loading a solid copper projectile that doesn't compress/deform as much as a jacketed bullet could lead to dangerous pressures with the same charge. The grooves both reduced the bearing surface and provided a void for the displaced metal, allowing the TSX to be loaded like any other jacketed bullet.

I imagine the elimination of "fins" was more a positive side effect.

But I've been wrong before.

Why would elimination fins be a POSITIVE side effect?
I love fins! (And Finns, too.) Putting fins on the '57 Chevy created an instant, enduring classic!

Keep the fins! Keep the fins!

The '57 Chevy ain't got nothin' on a '59 Caddy!

Regrettably, I don't own any fin cars. My only vehicle from that era has a stepside bed.

But I do prefer my bullets to be finless.

 

[Jdude]

I am sure the local Finns also prefer to keep bulletless.

They get shorter and narrower. According to my calculations and information supplied by others from this board, most Magnum rounds have projectile speeds approaching the speed of light in a barrel 20 inches or longer. Einstein proved ages ago that the bullet will appear shorter and thinner to those of us traveling on the Earth's surface at mundane relative speed.

I'm pretty sure this theory also explains why I miss the target so often

The reason you're not hitting the target is that you're shooting in the atmosphere. The bullets are obviously vaporizing before they get to the target due to friction, much like a meteor burning up before it hits the earth. Try shooting in a vacuum.

(This is a real problem with hyper-velocity projectiles fired from rail guns. There's a practical limit to how fast you can push the projectile before it burns up before reaching the target.)

That's my story and I'm stickin' to it.

I was really bored at work last night.......

And so were a lot of others, judging from the replies.....
( Including me, seeing as how I read all of them....)

 

[Stevie-Ray]

Huh?

The speed of light is about 983,571,056.4 feet per second. Find me any magnum round that approaches that, even the .17-50 BMG mall ninja magnum wouldn't come close.

Hmmm.....I get only 982,080,000 fps.And I can get that with my reloads in .45 ACP. But it has to be at least a 5 inch barrel.

Cannonball888: What kinda gun are you shooting that pushes things at relativistic speeds? I gotta get me one of those!

 

[230RN]

PS Nixie tubes?? You must be about tens days older than a stone to know about nixie tubes!

well, Dave P, if you look at my profile, you'll see that "I'm older than the rocks the dirt was made from." (Hm. Maybe you did already, come to think of it.)

And Nixie tubes have a kind of cult following nowadays. They mostly make clocks out of them. My son's desktop has a meter of LAN activity or something off in one corner, and the meter readout is composed of little images of Nixie tubes. If you Google Nixie tubes, you'll see a bunch of clocks with them... and, interestingly enough, a gorgeous clock in a large see-through plastic case where the readout is a big long Cathode-Ray Tube.*

>>>That Heisenberg joke was hilarious!<<<

Hmmmm.... I've got three of those old Compag Luggables with EGA CRT green-screen displays in them. Seems it wouldn't be very hard to remount the guts in a pretty plastic case and just run a little Basic program to display system time.... Hmmm....

 

[.cheese.]

oh..... so there is no gun that shoots at the speed of light?



You guys got my hopes up.

Nixie tubes and SCRs. When GE first announced the SCR, I designed a chronograph around them. The company I worked for had a deal in the contract at the missile range that they could patent only with permission from the Pentagon. We were three or four days late getting ours submitted to the patent office.

I'd sure like to have a nixie tube clock. Guess I'm going to have to do a search.

Incidently, 230RN, When G_d said "Let there be light" I was Utility Sgt. and pulled the switch. (First liar doesn't stand a chance. )

Heisenberg is out for a drive when he's stopped by a traffic cop. The cop says 'Do you know how fast you were going?'
Heisenberg says 'No, but I know where I am.'

The Uncertainty Principle...man this is getting deep.

Deep as in, "Where's my shovel?"

 

[230RN]

Armedandsafe....

SCRs are like a girl I knew once. Once you turned her on, she was uncontrollable.

Then I met a girl who was like a TRIAC. She went either way.

But my first girl was like a Thyratron. Very gassy. But she glowed when you turned her on.

And my Prom Date was like a Zener. Very high threshold, then she cascaded.

 

[Ske1etor]

I have been thinking about this since the original post and I think I have figured it all out. I cannot however relay this information because the back of my face hurts.

 

[Sistema1927]

Once we approach the speed of light we have out stripped Newtonian physics, and even Einstein is scratching his head.

I guess I'm in good company then? Because I'm damn sure scratching mine.

According to my calculations and information supplied by others from this board, most Magnum rounds have projectile speeds approaching the speed of light in a barrel 20 inches or longer.

Well, if my calculations are correct, when that bullet hits 88 miles per hour, you're gonna see some serious $^&%.

Naw, the flux capacitor is on the fritz.
