Reloading Podcast 565 โ€“ Jeff from Bulletology

And I thought they had a lot of promise.

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

There were things that needed to be done like some sort of protective coating, you know, like the bacon stuff that some of the guys use in order to shield that from

Firearms Radio Network (All Shows)

putting zinc onto the interior of the barrel.

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

And we needed to kind of take it a little bit farther, get nonlinear material properties and run it through some finite element analysis to understand how the material was going to behave.

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

We didn't get that far, but I thought it had great potential for non-toxic bullets.

Down below, if somebody wants to know if this is the guy who was on the Hornady podcast, the answer is yes.

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

Yeah, that's been a long time now.

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

Like I said, it's got to be, it's 10 years anyway, might be 15.

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

And yeah, the interesting part of that was we got to look at the behavior of lead bullets, kind of the gold standard for rimfire, rimfire 22, and compare it to the zinc.

And

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

The zinc, I thought, was not an identical match because the density is not quite as high as it is with lead.

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

But I thought it had a lot of potential.

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

Yeah, in terms of the diameter, the answer is yes.

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

The other details, I'm kind of drawing a blank on at the moment.

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

Yeah, so the real problem is you don't have a lot of gyroscopic stability margin with the length of diameter that you currently have with a lead bullet.

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

And when you go lighter, you lose...

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

taller moment of inertia rapidly.

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

So you might actually have to go shorter L over D to keep the thing gyroscopically stable.

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

Ah, okay.

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

So it was one of those, one of those you're in a, because of the twist of all the legacy right, you know, 22 rimfire rifles and handguns out there, you're really in a, in a, in a bit of a corner with regard to keeping the bullet gyroscopically stable.
