what's the difference

between M4's 70 gr sp at 100 yds and .45 70 Split Nose segmented bullet at 5 yds? Such a 223 hit is well proven to be devastating and the .45 bullet, split lengthwise, made of solid copper, will create TWO wound channels, diverging and each one will be wider than the 223 sp' channel. :-) The .45 bullet segments will yaw as they penetrate, (as they will be "seeking" a stable relationship in the media that is being penetrated. The fragile vital organ tissue that is "caught" between the diverging .45's wound tracks is going to be ruined by the high-velocity temporary gas cavity. Thus, the .45 split nose will have MORE effect than the 223 sp, same weight and same velocity. For the dummies, I'm not making any claims for what the .45 can do at 100 yds. You will miss a man, most of the time, at 20 FEET with a handgun, when you are being shot-at. So it's 20 ft and less that matters. and at such ranges, the .45 split nose offers a quantum leap in terminal effects. (as vs typical jhp's). i get it that you're too lazy to find out for yourselves, but the concept works. It's just a question of shooting the rds at ever increasing velocities, until the projectiles fly apart in flight and for the next ones, set the slitting saw in the mill about .020" less deep for the slit into the bullet. Then shoot some critters with such loads and see that I'm correct.

I'd say one relevant difference is that a .451" cylinder of copper weighing 70 grains is a mere 0.19" in length. Less than one-fifth of an inch from front to back of the cylinder.

We could gain some length by hollow-basing and careful forming of the front, but there's just not a lot there to work with. Going to be very limited trying to form that small an amount of material into sharp, pointy things when you're working with something less than one-fifth of an inch long to begin with.

like I said, feel FREE to post something worth reading yourself, instead of waiting for me to do it all

I think you're missing my point. I'm not saying that light, fast bullets aren't very capable. I'm saying "how do you do that?". For visual reference, a 70-grain .45-caliber bullet is darn near the same shape as a hockey puck. A hockey puck's thickness is 38% of its diameter, and 70 grains of copper creates a 45-caliber "puck" whose thickness is 42% of its diameter. Very close to the same in shape.



So how do we reshape a hockey puck's worth of material (while maintaining the same diameter) into something with a nose, much less TWO noses; in a shape that can be seated deep enough into the case to prevent setback or tilting, and protruding OUT of the case enough and with a shape conducive to reliable feeding? Remember, we're starting with a "puck" only 19 one-hundredths of an inch to begin with.

That's my question.

John, seriously. You've posted multiple times in multiple threads since I first asked this question two days ago. Yet you abandon your own thread (this thread) over a simple, completely civil question involving nothing more complicated than 3rd-grade math.

Only three possibilities here:
A - Is my math wrong?
B - Is it that you have a way to do it that I just haven't thought of? (That's always a possibility) or:
C - Is it that you just made this 70-grain, 45-caliber, split-point bullet up in your head, completely out of thin air..?

One (or more) of those three things must be true. I don't claim to know which one it is. But to ignore the simple question (a simple question about YOUR design and YOUR claims, that are the specific topic of YOUR thread) makes it simply appear that you don't have an answer.

Once again, we're back to the simple reality that "extraordinary claims require extraordinary proof".

Extraordinary claims without proof, must logically be considered as fiction until such time as proof is provided. So help move your claims into the realm of non-fiction, and show us how this bullet of yours is shaped. You say we should make some. I can't figure out how. Help me do so.
