Ammo. Slow&heavy or fast&light?

[Mr White]

I picked the 'training' choice. If you're well trainied, you can be deadly with a .22LR gun.

I picked "other." My preferences change between handguns and long guns.

I like bigger (heavier) pistol bullets with as much speed as can be mustered. The 230 grain .45ACP, the 147 grain 9mms, and the 158-180 grain .357 Magnums are my favorites.

In rifles, I like what ever mix of bullet and charge that garners a relatively flat trajectory. Sure, a heavy .45-70 will deliver a butt stomping on whatever it hits, but it has the trajectory of a rainbow. Guesstimating bullet drop or doing an equation is fun at the range, but IRL it's not all that great for hunting or defense.

Out of the choices, I'll have to go with big and slow. 2 main reasons: A bigger bullet is going to not only penetrate, but is much more likely to stay on the course it entered. Second, training is great and I recommend everyone do as much as they possibly can, but unfortunately in the bulk of situations people are overcome by adrenaline, fear, excitement, etc... and studies have shown that law enforcement are only hitting around 20 to 25% of the time.

If the shots hitting are infrequent, I sure want the biggest baddest bullet doing the hitting, so at least you have a better chance of stopping the threat before they can do something in return.

As usual, just my opinion.

I like the lighter projectiles in whatever handgun caliber I'm using. 185gr/45s, 115gr/9mm etc. I favor large caliber handgun rounds, but I like to keep bullet weight down so velocity remains as high as possible. At rifle velocities, I prefer smaller calibers than most, but I am primarily concerned with hunting as far as rifles go, and am consequently an accuracy/placement fanatic. A well-placed rifle bullet need not be especially large or heavy to do the job.

I agree with MPMarty have the best of both worlds with 10mm 180 grain at 1300 ft/sec = fast and heavy.

Training's best

If you shoot a fast bullet and can't hit what yer shootin' at then you'll just miss faster.

 

[MS .45]

I rarely use the lightest bullet offering for any particular caliber. For instance, in 9mm I use 124-147gr. I don't normally go for the 115gr unless I have found a good price on practice ammo.
