I disagree. Unless you are using reclaimed brass, the brass cartridge is, by far, the most expensive component.... The bullet is the most expensive component in ammunition. ...
We need to know more about what you're asking. 'grain' is a weight measurement. After that, the question you're asking needs to be clarified. Right now, it's a bit like asking "how does pounds affect a football player?"Hi guys. New here and to guns. How does grain affect a bullet? I've seen 9mm in 115,124,147 etc. thanks in advance.
Some will argue to use the largest bullet possible or will go with speed and a lighter bullet. I go with what I can shoot the best!I guess my question would be, does a higher grain have more stopping power, or is it better used for self defense.
Too many variables, such as bullet design, velocity, etc. to give a meaningful answer.I guess my question would be, does a higher grain have more stopping power, or is it better used for self defense.
Actually, all things being equal, (same bullet type--ie, 115gr Gold Dot vs 147gr Gold Dot), the heavier bullet will penetrate more than the lighter one. More mass=more momentum, harder to stop.For personal defensive purposes I go with the heaviest bullet (most mass).
I am not a ballistics expert by any stretch of the imagination, but it seems to me the more mass the more stopping power. I also worry about over penetration Therefore the more mass, moving at a slower velocity, seems more likely to encounter more resistence thus is lees apt to over penetrate.
However as many have pointed out the real key is whether the ammo you are using in your defensive handgun(s) works flawlessly time, after time after time.
I was referring to reloading ammunition, specifically 9mm. Once fired brass can be purchased for 2-4 cents a piece. The going rate for bullets is around 10 cents each it seems like. I still have a pretty good stash of 147gr Xtreme plated bullets at 7 cents each.I disagree. Unless you are using reclaimed brass, the brass cartridge is, by far, the most expensive component.
Of course, most of us that reload, retrieve our brass so we hardly ever have to buy more.
Not maybe--almost certainly.Maybe!
You are correct that the heavier bullet does penetrate deeper into "Bare Butted Jell-O"! But I doubt that either of us will be attacked by "Bare Butted Jell-O" anytime soon! I'm old enough to remember the Blob, but I think all the Anti-Bacteria soap has wiped him out!Not maybe--almost certainly.
If both bullets expand, the lighter bullet sheds velocity a lot faster and penetrates less.
Example--these are all Winchester Ranger-T bullets.
Note how even the warp speed .357 Sig bullet doesn't penetrate as far as the 147gr 9mm.
Well, one small issue. In 9mm, especially through barriers, you will get a plug that stops the hollow point from expanding. The PDX round seems to be, from the tests I have seen, prone to not expanding. So in the case of the 124gr bullet that goes deeper than the 147gr, if the expansion was less, that would make sense.You are correct that the heavier bullet does penetrate deeper into "Bare Butted Jell-O"! But I doubt that either of us will be attacked by "Bare Butted Jell-O" anytime soon! I'm old enough to remember the Blob, but I think all the Anti-Bacteria soap has wiped him out!
Below is the terminal ballistics (FBI full testing) from Winchester's website for the Winchester T-Series:
Terminal Ballistics: Penetration 9mm 147 gr T-Series
Bare Gelatin - 13.9
Heavy Cloth - 14
Wallboard - 15
Steel - 17
Autoglass - 10.8
Terminal Ballistics: Penetration 9mm +P 124 gr Bonded (PDX)
Bare Gelatin - 12.6
Heavy Cloth - 18.2
Wallboard - 11.9
Plywood - 15.8
Steel - 22
Autoglass - 12.7
So if the "Bare Butted Jell-O" is wearing heavy clothing the 124 gr goes deeper! OMG!
Again the correct answer is "Maybe!"
Terminal Ballistics: Penetration for the 125 gr Winchester T-Series .357 Sig:
Bare Gelatin - 12.3
Heavy Cloth - 14
Wallboard - 12.7
Plywood - 11.8
Steel - 21.5
Autoglass - 11.7
Terminal Ballistics: Penetration for the 125 gr Winchester (PDX) Bonded .357 Sig
Bare Gelatin - 12.5
Heavy Cloth - 16.9
Wallboard - 14.7
Plywood - 16
Steel - 21.7
Autoglass - 12.8
So as you can see from above even the model of bullet can effect the Terminal Ballistics!
Again the correct answer is a definite "Maybe!" :wave:
