I have a 14.5" barrel at a 1:9 twist. Within 100 yards, which ammo would you use the Hornady TAP 55 grain or the 75 grain? Why?

I've heard that that the 1:9 is good for bullets over 75 grains? Is this true and what damage would it do to my AR15?

The bullet isn't going to damage your rifle. Heavy bullets in too slow a twist simply won't stabilize in flight. That's just basic ballistics.

Frankly, it's not going to matter which bullet you choose. I don't need to get into details about terminal ballistics, yawing in flesh, overpenetration, etc. Just flip and coin.

That said, I would personally use a shotgun for home defense. For one, unless you're using an AR in a detachable configuration, I wouldn't want to use a rifle that I have to use a tool with in order to reload it. Second, even if you are using a registered Assault 'Weapon' according to the State of CA, you don't want to use it for a home defense situation. Even if you are in the right, you're going to have to give up the rifle to the police for evidence. God knows when you'll get it back. That's why I stick with a trusty Remington 870. If and when it's used in a clean home/self defense shooting, I won't feel too bad when they confisicate the gun for evidence.

I agree with ocabj. Use a shotgun for home defense as they are cheap and easy to replace...

The 75-77gr. seem to have better terminal performance but a 1/9 twist may not properly stabilize bullets in that weight range. You'll have to try it out in your rifle. Truthfully, for home defense, I still prefer a shotgun, but YMMV.

I m not saying that 75gr will definitely not work.... but if you have a 1:9, stick with light bullets.... so btw your 2 listed selection.... go with the 55gr.... yet... I rather use a pistol than an AR in home defence situation...

Again, use a shotgun. Get a $200 Mossberg and some #7's. It will do the job and not go through sheetrock. A 223 will go far beyond your home and that's way more liability than you can deal with.

+1 on the shotgun, the artillery of home defense!

Even the frangible 223 will go through 0.25-in mild steel like butter.

Anything that won't go through sheetrock, won't do the job.

Won't go through sheetrock? Yes, it will help eliminate overpenetration, but will still go through sheetrock, especially if it is still in the wad and the shot does not start to seperate from the cup will around 15 ft or so depending on the barrel and choke config, and figuring that most self defense shootings take place inside 15ft, especially in the house, the shot will still be in the wad.

I would hope that your 14.5" barrel has at least a 1.5+" permanently-attached muzzle extension so your rifle stays out of NFA/SBR territory.

1:9 twist? Some 50gr V-Max would absolutely explode on impact. I'd avoid the 75gr TAP. You really would benefit from a 1:7 if you're shooting heavier than 70gr.

I would suggest frangible ammuntion. Won't over penetrate, and if I remember correctly, no one has ever gotten up after being hit by it.

Shoot the heaviest thing your rifle will accurately shoot.

Take some 75 gr to the range and try.

I always favor "more bullet."
