What is the proper name for this configuration?

[policerevolvercollector]

I ran across some of these in my ammo drawer. What is the name for the type of projectile?

Best,

Looks to be a plated flat point bullet.

I've seen them referred to as a Truncated Cone (TC).

 

[semperfi71]

Also referred to as a truncated cone bullet.

 

[policerevolvercollector]

Thanks!!!!

They are good paper punchers. Almost as good as a SWC, but they work better in bottom feeders than SWCs due to the smoother profile.

Personally I'd call it full metal jacket flat point (FMJ-FP).

The design is indeed called a truncated cone solid bullet, first developed by the Germans early in the 20th century, in both 7.65mm and 9mm calibers, for use in the Luger pistol. The German military dropped the design in favor of a round-nose bullet in 1916. The Italians used the same bullet shape for their 9mm Glisinti 1910 pistol cartridge (very similar to the 9mm Luger, but less powerful). I can't comment on the relative advantages of either bullet shape.

TC is way easier to say & type

Interesting fact: the original German military 9mm load featured a very effective TC bullet. So effective in WWI, the Allies accused them (probably knowing better) of using expanding ammo forbidden by The Hague Convention in 1899.

The Allies threatened to execute any German soldiers caught with it, allegedly causing the Germans to switch to RNs, though there's speculation the switch was also to make the 9mm function better in SMGs.

Ironically, the Germans made the same complaint/threat regarding American trench shotguns.

I disagree. This is a Truncated Cone in a revolver caliber. Steeper ojive and smaller meplat.

I call it either a TC, JFP or PFP depending on how I feel on the day.

I use these in 200gn in my :45 ACP and they are fadmore accurate than either lead or jacketed RN.

The bullet pictured has no ogive at all. Or if you prefer, a secant ogive of infinite radius, meaning that it has no curvature. See my discussion at http://smith-wessonforum.com/reloading/535837-meplat-ogive-post139757371.html?535837=#post139757371

I guess anybody can call it anything they want.
Fiocchi calls them a truncated cone
Xtreme calls them a truncated cone
Winchester calls them a truncated cone
Matt's Bullets calls them a truncated cone
J&K Cast calls them a truncated cone
Remington calls their 22LR of the same shape a truncated cone
That seems to be the industry accepted description for a bullet with a flat nose, straight tapered sides that isn't a traditional SWC design.

The Truncated Cone (TC) profile technically has no ogive since an ogive is defined as a form of elliptical curve.

The qualifier is the materials. FMJ, Hardcast, plated, etc.

Since the OP did not specify caliber or say whether it is jacketed, plated, or solid copper, the only thing that can be said with certainty in response to the original question and photo is that it is a TC bullet in a rimmed case.

Seems to me that anything beyond that it is speculation and angels dancing on the head of a pin.

 

[dannyabear]

rnfp is correct I think , round nose flat point; a trunucated bullet has more ^ to it

 

[scattershot]

PTC - plated truncated cone.

 

[rwsmith]

Yeah, I'd call it..

...a truncated cone, plated or jacketed. Flat nose bullets still have a round ogive with a flat tip, but that one has straight sides.

They are good paper punchers. Almost as good as a SWC, but they work better in bottom feeders than SWCs due to the smoother profile.

Besides feeding smoother also way cleaner then LSWC loads

I use a bullet that looks just like that from Rainier.
It's a plated 240 grain 44 they call a total copper jacket
The shape they simply call a flat point.
I call it a plated flat point.
Their hollow point is that exact bullet with a hex hole punched in the nose.
I like these bullets and they have a slight hollow base I believe helps them obturate to the chamber mouth and bore.

I would call it a FMJ Truncated bullet.

Same here.
