TCFP???

[Texasgrillchef]

After an exhaustive web search of people comparing tcfp to rnfp I still have no clue what a TCFP is.

I get the FP probably stands for Flat Point, but what the heck does TC stand for?

I also don’t see much load data for a .452 300 grain hard cast TCFP, but do see it for an identical bullet in a FP. (no RNFP or TCFP, Just FP) however, in lead hard cast. Are they interchangeable as far as load data goes?

I am looking at using this in. Henry 45 colt lever action.

TCFP = Truncated Cone Flat Point???
RNFP = Round Nose Flat Point???

Just a guess, especially that first one.

Pretty sure it means Truncated Cone.

Google it. Lots of examples.

So is the load data the same though?

example...

I see load data from two sources for a 300grain FP hard cast lead.

However what I have is 300 grain TCFP

I also see data for a 255grain SWC but no data for a 250 grain RNFP.

So where is the data for those bullets? Not listed in Lyman, Hornady, Western, Accurate or Hodgon.

Also I don’t see any of the heavy load 30k round data at all for those bullets. Only for other top dollar bullets such as Barnes, Hornady, Lehigh Defense, nothing for just lead.

YET... I can easily find “+P” lead load ammunition for the 45 colt to buy. Such as from Buffalo bore, and Garret. I can find what appears to be the same lead bullets they are using. 250 and 300 grain RNFP, but no +P data to load.

Any ideas?

When I have a “same material, same weight, same diameter but different profile” issue, If the bullet is of the same material and will be seated to the same depth in the case, I’ve started at the minimum load listed and worked my way up to the velocity-accuracy I was seeking.

stay safe.

Oh, here are two .358 125 gr bullets.

The lead is the RNFP, note the shoulders of the bullet are rounded towards the flat nose.

The plated is a TCFP, picture the straight shoulders being like a pyramid with the upper point cut off flat.

Both work well in lighter loads for my J-Frames/Colt Cobra 2”.

Stay safe.
