They also claim to increase the quote unquote porosity, which I don't really think I understand very well.

But that's another geometry option for folks.

Firearms Radio Network (All Shows)

But it's not it's not it's much less commonly used.

Firearms Radio Network (All Shows)

then the flake, the sphere, or the single perf geometries.

And up at the top, we've got kind of what chemistry each of the powders can employ.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

And, you know, the single base powders are basically...

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

nitrocellulose only is the primary constituent there are other things in it like stabilizers and deterrents and that sort of jazz uh double bases use uh you know anywhere between oh i'm going to pick a number eight uh say 12 or 13 percent nitroglycerin uh in addition to the nitrocellulose so um so that's that's um

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

kind of what's available to the shooters, okay?

Firearms Radio Network (All Shows)

And double base powder, because the nitroglycerin has more energy than nitrocellulose, you get about 10% more energy, which gives you more, has the potential to give you more velocity.

Firearms Radio Network (All Shows)

Yeah.

Firearms Radio Network (All Shows)

So like anything else in life, there's no free lunch.

So the nitroglycerin increases the flame temperature of the propellant, which makes the barrel life shorter, generally speaking.

Firearms Radio Network (All Shows)

So barrel life is really largely determined by the firing schedule.

How fast are you firing the

Firearms Radio Network (All Shows)

How much propellant pushing down, pushing out through the barrel and how how hot does the barrel get?

What surface treatment does it have?

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Does it have chrome plate?

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Does it have nitride?

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Does it have nothing?

So so that's part of the part of the.
