.40 S&W hard barriers.

Which .40 S&W load has the deepest penetration on hard barriers such as car doors, walls etc?

Thanks.

Here is some info on velocity and energy but I have not seen a large list of
comparisons for penetration yet.

A bonded 165 or 180 should be best but really almost anything 155 and up should be sufficient.

Speer Gold Dot 180Gr penetrates very well. If you want penetration on hard barriers I'd go with a bonded 180gr however the 165gr. GD does well also. Some info below.

Penetration typically increases as the bullet weight/sectional density increases. From Double Tap in .40 S&W;

Quote:
DoubleTap .40 S&W Penetration / expansion
135gr. Nosler JHP @ 1375fps/567fpe - 12.10" / .72"
155gr Gold Dot JHP @ 1275fps - 13.00" / .76"
165gr Gold Dot JHP @ 1200fps - 14.0" / .70"
180gr Gold Dot JHP @ 1100fps - 14.75" / .68"
200gr XTP @ 1050fps - 17.75" / .59"
I expect that DT's 200gr WFN would give the deepest penetration against the barriers you describe.

I second the 200gr. WFN. Suffice to say, the bullet would go in one door and out the other.

Uh, you two guys mean this: And I 3rd it. ha

It ain't DT, but it'll go through a Grizz from front to back. Goes through elk like a knife through butter, and has NO fear on bones.

A non expanding load like the Double Tap 200 grain FMJ.

A small advertisment here: You guys who love HC bullets check out my good friend at Hunter Supply. JR is sending me, this week, 2,500 HC bullets 500 each in 5 different calibers in 9mm, 10mm, 357/38, 45acp, and 44cal, to run test on this new line he just started. Pentagon HP HC.

I'm happy he ask me on board to help run the test. Bench time looks like...

I'm not a big HP fan with HC bullets, but these may change my mind after the testing. We'll see. Now I need a 55 gal barrel of powder ! haha.

Stay safe !

Well, although my testing for JR owner of HS bullets in NM, has not begun, on the "new line," of HP's that is, until the UPS truck gets out here. Ha.

I have been a friend of JR's for a good number of years, and we have shot tons of Hunter Supply cast bullets. (the non- HP style will go completely length ways through a big Grizz in a 45LC.) They also usually blow through large bison, and through elk as well. Square shoulder hits are no problem..

The devistation of these bullets are absolutely incredible. I've used HC bullets all my life sense I was a kid, in the big bore hog legs, and also in semi auto's, and some lever guns.

I've no doubt, before my testing even begins, that these "new" HP HC will be extremley bad news on a coyote or an elk ! As JR owner of HS knows, I am not a fan of HP hard cast bullets. But I do know the formula (mixture) of the contents of these bullets, and therefore already know they will be very deadly on game. Even Moose and elk in the larger cals such as 44mag and especially the 45LC. This "new style" will give those who like HP's in their hard cast bullets, some of the expantion they crave..

Anyone with a desire to use these HC in their semi's or their revolvers, and have not yet experienced the tremendous penetration and damage done to bone and the quake of smashing power they have, needs to try them.

Been kinda off track on this old boys thread. Best jump off for now... Sorry OP

Thanks.
What do you want it to do after penetration. Is it pure penetration, or do you want to know what would do the most damage to a person after pentration? Are you looking for something that is effective but has a limited penetration? Why do all of your threads get locked out?

I Would like to know what common household furniture is good for cover. Can I use my fridge for cover? Old school TV? Dressers?

Sounds like you need to visit the "furniture bullet penetration test" thread.

I figured since he posted this "I'll probably go with DPX in 165 thanks." he was referring to a JHP SD round that works well against barriers. For pure penetration I agree with the others a hardcast or FMJ would be best.

I have fired several rounds of .40 165g Gold Dots into an old car door. None penetrated to the other side. Granted this was a mid 80's Crown Vic so newer cars might not be as solid.
