12 GA slug ammo question- armor piercing qualities?

[Jarnhamar]

While buying 12GA slugs someone suggested I buy the Challenger magnum slugs. He was saying they were pretty much as close as you can get to armor piercing slugs legally.  Other slugs like the federal slugs expand a lot more since the lead is softer but they don't penetrate as much.

How accurate was that guys statement?  I figured I'd try some anyways so I bought them, just haven't found anything to test them on yet.

I wonder if Teflon paint would survive muzzle velocity. Wish I had a titanium plate to send you. I am curious now too.

...should be good for 3/16" armour...  :nod:

I'll test it out on an old car door or something, then I'll be able to sleep at night  ;D

Even the harder lead won't do well. If punching through armour with a shotgun, you should go with a rifled barrel shooting sabot slugs. Then you will get some armour piercing effect and good terminal effects.

I had a rifled slug bounce off a car windshield at around six feet.  I have little confidence in the AP qualities of shotguns and lead ammo.

The problem is that most sabot slugs are designed for flesh and expansion within that medium. Speaking to C.O.'s tests they did on bear carcasses showed average penetrations of  6" for Foster style slugs, 12" for Brenneke and up to 16" for rifle bullet style sabot. You could make a slug optimized for armour piercing, but the shotgun is not your first choice when you can use .308.
