Powder Differences

[Leo Tanner]

Been shootin 3F in the 51.  I like it alot, but was recently offered a good deal on a case of 2F. 
What are the differences any of you have noticed between the two?  Should I make the purchase, I'd be paying about half price.

[Delmonico]

The smaller FFFg burns a bit faster, you might have a bit more fouling with FFg and you might loose a bit of velocity but with out a crono or weighing your dirty patches I doubt you'll see enough differance to even notice.  I never did, some may say differnt, but I doubt in a blind test that would hold much water.

Oh forgot your pressure will be slightly higher.

[Sir Charles deMouton-Black]

Heh! Del!  Won`t the pressure be LOWER with 2F than 3F?

That 2f would make great shottie loads.

[Mako]

+1

[Noz]

The only difference I can see is that the FFFg meters from the powder flask faster than the FFg. For what we're doing, buy it!

[Fairshake]

A little lower velocity and less recoil with more hard earned cash left in your pocket. Don't seem like that one is hard to figure on what to do.

[Delmonico]

Tis what happens when I try to post and answer the fhone at the same time.

Should a read "will be lower with the FFg.   And te durn "Black Sheep" a the bunch caught me.

+1

I've seen that on other boards from folks who always want to one up-manship everyone.  Been better if ya 'splained why the pressures would be lower with FFg.

[Leo Tanner]

I figgued it was cause the bigger granuals can't compress as much as the smaller.  I'm sure there's more to it than that.

     By the way, it's Goex, an unless yer a local friend of the guy sellin it, odds of gettin yer hands on it are slim

Nope, any time you have equal amounts of powder where one is faster burning than the other the pressure spike will be higher with the faster burning powder, a bit more molly-cules get to burn and turn into hot gasses before the projectile moves enough to make enough space to relive the pressure.  Of course this is not so when comparing Black to Nitro since Nito powders can develope higher pressures.

A bit more complicated than that, but good enough unless you want to study chemisty.

     Thanks, knowledge is power an that makes complete sense

When they was tryin' to make somethin' useful out of a cripple they sent me to school for a while, them chemistry and physics classes were worth the trouble. 

Course they decided I was to beat-up to be useful, guess I showed them.

Delmonico,
You are looking for blackguards where there are none.  I made no attempt to pile on, just agreed with Sir Charles because he was right.  And to the second part I disagree, an explanation  of the relative burning rates and pressures would have appeared sophomoric.  That's what the different "F grain" designations are all about.

I'm sorry you don't like it but I think the +1 is a good way to agree and help create a consensus without being pretentious.

Have a nice evening,
Mako

Well as I figured all along, you are one of those who only values their own opinion.  Plenty of them in this world, my explination is simple, because that's all it needs to be.  You want to fill the 20 or 30 pages it would take to get it in proper terms, go ahead.

Then twas my original question that was sophmoric.  I didn't know what the F degs meant other than grain size.  I always ask "why" an as I said, knowledge is power, I like to learn.  Especially when dealing with things that go BOOM.

Howdy

It is a surface area thing. Each grain of Black Powder burns from the surface in towards its center. Smaller grains have proportionally more surface area than larger grains. So smaller grains burn faster, all other things being equal.

 Without getting into any arguments I will also point out that the larger granulation will also give you more sparks and flame flying from a handgun barrel. I like the sparks and flame. Plus I do believe the flame is bigger. I haven't tested that scientifically, I have shot both 3f and 2f on cloudy, rainy days when I could really see the fireball from behind the gun.

Well now that there alone would make the go at it worth it  
I like evening shoots, and love the flame.  Just wanted ta mske sure nothing would get fouled up if I switched powder

     Driftwood, that makes sense, with the surface area causing the faster burn, thanks.

[Leo Tanner]

And while I'm askin questions, what the heck does the "g" stand fer?  I've seen old cans/kegs that don't have it.  Is the powder without the "g" different?

[Delmonico]

Leo, the correct answer to yer question is "Glazed", it means that the powder has been tumbled in graphite and the cornersrounded off. An A or nothing means it unglazed.  Not sold in this courty for sporting use any more, was cheaper.

Leo,
I sent you a PM. I'll talk with you later.
