Quick ammo question

[Bic]

I've heard the expression 'Truncated Metal Jacket', although I don't know what it means....

I've heard that also and I've guessed it was a jacketed Keith type bullet configuration rather than round nose.

Think .40 S&W target ammo....

I have shot it and recovered bullets from various backstops,....it flattens to about the diameter of a quarter shooting through water jugs.

Truncated is a geometric form.  Think of a tapering cone with a flat top rather than coming to a point.

Full metal jacket ball ammo has a "blended radius".  Now make that flat like .38 WWB ball ammo.  That would be "truncated" as it's flat on top for use in lever action rifles.

Commonly known as semi wadcutter?

Or TMC - Truncated Metal Cone.  SWC has a sharper edge that cuts targets much better.

Looks like it comes in both RN (round nose)  and FN (flat nose) configureations if you look at the product listings, also something called RHT ?

From Speer's websight:

Lawman Clean-Fire—The Indoor Training Solution
If air quality in indoor ranges concerns you, Speer® has the ammunition to set your mind at ease. Lawman® Clean-Fire® is loaded like regular Lawman except for the primer and bullet. The ignition power comes from our patented* Clean-Fire primer that contains no lead, barium, or antimony.
The bullets we load in Lawman Clean-Fire are Speer's TMJ®. The lead core is completely and seamlessly encased in jacket material so powder gases can't burn lead off the bullet base. This design is superior to other makers' "base cap" bullets where the caps can loosen, leaking lead and destroying accuracy.
Lawman Clean-Fire leaves the range air and your firearm cleaner. Fired cases don't show the usual soot coating you see in most regular ammunition. Velocities and bullet weights are the same as most Gold Dot® products for realistic practice.
When you need to clear the air, reach for Lawman Clean-Fire, your training solution.

When directed at individual shooters this is nothing but marketing BS.
The only way that components can effect air quality in a range is if only that ammo is used.
As an advertisement to range operators it may be true , but on an individual basis it will make absolutely no difference since the guy before, or on either side of you is probably not using it.
So all you are doing is causing yourself to either waste the brass or have to sort for 2 different primer sizes.

Okay, the question is answered (sort of). I made it to Gander and bought a box of the stuff today, I mean, at $12 per 50 why not? According to the box it is training ammo for LEOS that mimics the weight of Speer Gold Dots, but it is pretty much lead free in the primer and the entire bullet is jacketed. So its NOT "truncated metal jacket" (which I was hoping for), but total metal jacket. Basically its a lawyer round designed to keep the environmentalists happy on outdoor ranges and OSHA happy on indoor ones. Still, its a box of Speers for $.24 a round. I'll take it.
