Is TMJ essencially a jacketed SWC?

 

[NYPD]

Taken from an online source:

TMJ is a thick (thickness varies by manufacturer) plating over the entire bullet. With FMJ bullets, the jacket is formed over the nose of the bullet and rolled over the edges of the base, leaving lead exposed in the middle.

Ah, total metal jacketed.

My source referred to "truncated metal jacketed," as in flat nosed.

basicly the same thing i had some .38's 100 rnd bulk wwb packs from walmart.. they make a nice clean cut threw the paper.. i believe the .40's also come like that.

I think it depends on the caliber being discussed. Most of the 40 S&W ammo I've been around were shaped more trundicated (whatever shape that really is, possibly some variation on a cone??) than like a traditional ball round (ala 45acp or 9mm).

does'nt truncated simply mean cut off? or abruptly ended?

i beleive it's just another term for flat nose.. the 38spl's i had would best be described as a flatnose fmj.

the bulk pack .40's i seen was similar to the 38's i had.

With an "MJ", of course. Which I think is why it amounts to a jacketed SWC.
