How would the energy in a pound of Bullseye powder compare to the energy in a gallon of gasoline ?




Mike

Gasoline would be about 10 sticks of dynamite.

1 gallon of gasoline = 1 stick of dynamite. Hasbeen

By weight, a gal of gas is roughly 8 lb. Compare it to 8lb of powder or do it by volume - a gal of powder.

Gasoline is closer to 6 pounds to that gallon.

That is an interesting idea, Mike.
Gasoline will flow easily through your powder measure, but may be rather messy.

Be sure to video your testing, for the Youtube audience.
Be careful, now.

We use 105 octane not E85

The energy density of smokeless powder is MUCH less than half that of gasoline. So a gallon of gas is more like 20 lbs of smokeless powder in energy.

I don't have any idea of the energy of smokeless powder. But Tolulene is the second T in TNT. Very close relative of gasoline. Hasbeen

Found the approximate energy densities by Googling around:
Gasoline - 47.2 Mega joules/Kg
Black powder - 3 Mj/KG
Smokeless powder - 4.6 Mj/Kg
Gasoline varies by +- 4% and powders will vary some according to composition.

The density of gasoline is about 6.15 lb/gal so if my math is correct it takes about 63 bl of smokeless powder to equal the energy content of one gallon of gasoline.

Now go on Amazon and order a couple of pressure cookers.... I dare ya.

Here's a ballistically-interesting way to think about the energy density of gasoline from a Conservation of Energy standpoint:
- Let's say your truck has about a 24-gallon tank.
- And let's say you normally get about 400 miles between fillups.
- 24 gallons of gas doesn't look like much, does it? And you're pretty comfortable driving around sitting on top of it, right?
- Well, if you could make a cartridge and barrel combination where the "bullet" was your truck (real-life size and shape), and put just 24 gallons of gas behind it, and could burn it with the same efficiency as your engine, then pulling the trigger on that particular handload could shoot your truck through the air for about 400 miles.
- Now that last "if" (efficiency) is a biggie. No way a cartridge could get even close to that, so let's say that between combustion and increased aerodynamic drag you'd lose 99.5% of the effective energy because of that problem. That's still enough that your truck would stay airborne for about 2 miles.

Gasoline has a LOT of energy.

Yes, gasoline carries a lot of energy. Fortunately for us, it does not also contain its own oxygen supply.

OK, I am going to have to start loading with unleaded now in the condor areas

What kind of barrel life could you expect ?


Mike

When shooting trucks, it's best to use a Sabot. It provides a better fit to the bore.

Sooooooooo about .5 grn of 87 octane for a 45 acp when compared to a titegroup load of 4.6 grn that would be a lot of rounds out of a gallon of unleaded!

Hey, hold my beer..................

Think of it this way.

Volume in grains of powder pushing a bullet down a cylinder.
PSI cabin pressure.

Tiny spurt of gasoline pushing a piston down a cylinder.
PSI cabin pressure.

A V8 engine fires several thousand rounds per minute at highway speed.

You couldn't shovel powder in fast enough with a 4yard loader bucket to propel a vehicle.

Besides that, factoring in burn rate and other differences would so boring and so tedious you'd quickly find yourself with no audience whatever.

Do you find the S10 to have less recoil than an F150?

What about accuracy RE: Tundra vs Ram?....

You may need a magnum primer is compression is high.
