9mm 115 vs 147 grain?

[kerb]

If you're shooting factory ammo, the 147-grain bullet should work well in your Glock in either plated or FMJ. What wasn't mentioned in the previous posts is the use of unplated lead bullets mainly used by reloaders. Glock recommends NOT using unplated lead ammo, and there are stories around that say Glock will void the warranty on the gun if you do. You can avoid this problem by swapping out your stock barrel for a stainless barrel, a cost of $95 to $165, depending on brand.

I heard that. I wonder why? Since lead is softer than copper one would think it is easier on the barrel.

Thanks Captain obvious. Many people will say that your gun shoots a particular load/brand etc. better than anything else. So far from my experience, I see no major difference between any ammo I have shot in the 9mm. And I have now shot three different kinds.


Thinking about it more thoroughly, I imagine this is meant for long range firing, not 30-45 feet.

You should be spending more time on learning how to shoot and less time on what ammunition you're going to miss with. Capt. Obvious out sparky.

Glock uses polygonal rifling which seals the bore better than land and grove rifling, it also allows lead build up differently which can result in unsafe pressures in the barrel.

One shot stop ratio's are junk science that have long been discredited.

Really? By who?

I agree 100%!! Every course I've taken teaches the same thing. You keep squeezing the trigger until either you need to reload or the threat has been eliminated. That one shot hype is gonna get someone killed. There are never 2 targets that will react the same to an impact. One may go down on the first round, the 2nd may close the gap and beat your butt with 3 or 4 round in him.

Of course, but the one stop ratio is not to say that you should only shoot a person once but what the chances are of stopping that person with one shot. It's a benchmark.

You're absolutely right, as Jesus from the Big Lebowski says "gonna pull the mother****** trigger until the gun goes "click"

Each to their own opinion of course. For me I tend to go for the lighter, higher velocity load, which obviously has less recoil and is easier on follow up shots.

.40 - 165gr GDHP or CD
.44 - 240gr XTP
.45 - 185gr GDHP or CD
9mm - 124gr GDHP or CD

I think it's interesting to note that Hornady tends to go to a lighter load for the Critical Defense and Critical Duty line of ammo.

Not trying to be disrespectful but you would be better served practicing and experimenting with different loads than spending money on ballistic gelatin tests. There are many such tests on youtube. Take advantage of them.

After you have mastered your weapon if you still feel the desire to do gelatin tests go to it...just seems to me it would be more fun shooting.

147gr will penetrate further than the lighter loads...something to consider when people are wearing heavier clothing during the winter season.

I have always preferred a heavier bullet... I had some corbon +P 115 grain JHP rounds that would not penetrate more than 2 milk jugs full of water in our redneck ballistics lab.
The 147 grain loads did much better blowing up 3 to four milk jugs full of water.

I trust my redneck ballistics lab because it is an environment I can duplicate time and again. It is fun and good practice shooting all them jugs an such. And mostly it is trigger time which equates to fundamentals, Practice, practice and more practice.

I really like setting up multiple milk jugs on stands and engaging multiple targets while closing on the target berm in a walking while shooting drill.

Seriously,
I carry what I like and what works well in pistol regardless of if i am carrying a 9MM or my .45ACP

I do like a heavier bullet. but that is my preference. YMMV

Doing an internet search for ..... 9mm ballistics gel test .....will bring up tons of information about the differences between different bullet weights and their performance in ballistic gel.

It will also bring up comparisons between the performance of 9mm and other calibers.

What I have found interesting is that, at least in ballistic gel, the common self defense calibers seem to penetrate nearly the same amount... 12 to 14 inches.

One other thing that search will do.... it will keep you busy for quite a while. :smile:
