Really? Where are you?

Heavy(longer) bullets in rifle calibers "fly" better , retain their velocity at long range better and therefore hit their target with more energy. This I know. Over penetration and collateral damage, with a pistol caliber I can understand. My question is- if terminal ballistics of 2 given handgun bullets were equal( expansion, penetration) why would you not want the one with more energy ?

More energy does not always translate to more penetration. Here's the notes I made on Uw 10mm.

grain-fps-fpe-penetration

135-1600-767 *10.5"* (G29-1440-622)
155-1500-775 *12.5"*
165-1400-718 *12"*
180-1300-676 *17.75"*
200-1250-694 *16.125"*

Look at 180, lowest energy yet more penetration.

Thanks I see. but with this data if you are shooting a thin person in a crowded room the 155-1500 would be a better duty round ? Another question, if the 180 goes through and the 155 stops short(thus transferring ALL of its energy to the target) would the 155 have more " stopping" power ? I appreciate your patience with me I am primarily a long range target shooter.

if they reach the vitals then the job is done.

If you load up with 135 or 155 and then run across a fire breathing doped up biker I think you'd better run.

 Guess I will load up with 180's next time I am in Sturgis lol.
Actually the addiction has manifested itself, I just ordered some UW 180-1300's before I knew about the bikers.

I haven't really heard anything about a bullet punch through a person and injure another person behind in any news. Then I would think that the energy was expended going through one to have another injured but that's with a hollow point that expanded.

A solid core or a failed hollow point probably will cause injuries by going through someone but probably through only tissues and not encountering bones. It's really hard to say what the outcome will be so we have the cardinal rule #4 which is to be aware of what's beyond your target.

Hydrostatic shock isn't a big thing with handgun calibers. Now get hit with a 180 from a 300 Ultra Mag, and everything inside your chest cavity will be wrecked. Ever shot a deer through the heart &  lungs, but the stomach is busted too? You just can't get that with a handgun. That's why he's saying make sure you can penetrate vitals.

My idea of hydrostatic shock is making a baddie cry because he got shot and it hurts. 

Practical hunting story- I hit an elk @ 746yds with .300RUM 180 scirocco through the heart. Heart was completely pulverized, no exit wound, elk dropped in his tracks.(I tell you it was worth every bench session, sore shoulder and scope cut). Years before I hit an elk at 335yds with .338WM 200gr CT ballistic tip, bullet passed through the edge of the heart expanding partially and exiting. Had to track the elk for a 1/4 mile through some deep timber(not fun)(and less fun getting it out).

I got the new Hornady catalog today. They have the .41 Cal 190gr FTX listed (on page 55). They show its effective performance range is from about 1200 fps to 1800 fps.

If you took a razor blade and cut the tip flat, it might work good out of a 6" barrel.

I might have to buy some to try out.

I got the catalog in the mail today too. But where did you see the target velocity?

Nevermind, I see it. I thought you had found a master chart or something I missed lol

But you are thinking exactly like I was when I asked about that bullet to Hornady. Please try and let me know. With the point cut off the tip, it's no different than Critical Duty or Critical Defense.

It may be a while before I can try it. I have no money and no place to shoot close by.

I understand that completely, the holidays have killed me.

At my old place I had a 100 yard rifle range set up, permanent bench and all. Here I have to be careful which direction I shoot and expect calls when I do. Luckily I think my father-in-law is going to use his front end loader to build me a pistol range back stop.

The three on the left are 38 Cal 140gr FTX #35745, and the one on the right is 38 Cal 140gr XTP #35740.

from left to right. Full point FTX; cut point FTX; removed point FTX; XTP.



The 38 cal FTX has a range of 1200 to 1800 fps. The XTP has a range from 800 to 1600 fps (these ranges seem to change with every catalog they produce)

I planned resizing these 38 Cal bullets to 0.356, and using them in 357SIG and 9x23 Winchester cartridges.
I don't think there is any reason to use the FTX in a semi-auto pistol. The maximum velocity I can get in a 6" barrel is about 1400 fps. I think the XTP would work better at that velocity and lower. The XTP also has a higher ballistic coefficient.
