talon:
Thanks for the link and directions.
Having read the information there, I really doubt that this rule would (or should) effect the making or sale of bullets like mine.
"921(a)
(B)
The term ''armor piercing ammunition'' means -
(i)
a projectile or projectile core which may be used in a handgun and which is constructed entirely (excluding the presence of traces of other substances) from one or a combination of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium; or
(ii)
a full jacketed projectile larger than .22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of the total weight of the projectile. "
Paragraph (i) refers to projectiles that do not contain any lead, which is not the case with heavy jacked bullets we're discussing, and is, therefore, not applicable.
Paragraph (ii) refers to jacketed bullets, and in it, the words "designed and intended" would have to be intentionally mis-interpreted to mean hunting bullets intended for use in big game hunting rifles. However, knowing the anti-gun bias of certain players in this debate, sometime in the future this type of deliberate misinterpretation may indeed occur (particularly if "they" gain power).
