Any recommendations?

What do you mean by "HD plan?" Home Defense? If so, you don't need frangible. Get good hollow point ammo and stay with 55 grain.
We did some extensive testing on .223/5.56 ammo when we switched from the MP5's to M4's. Everyone was afraid of over penetration.
What we learned, and it's going to sound counter intuitive, is the 9mm was over penetrating, more than the 5.56.
The heavier 9mm was plowing through 2 X 4's, sheet rock and many obstacles, while the lighter .223 was more susceptible to deflection as well as slowing down and being stopped by solid obstacles.
If you were to fire a 9 vs 5.56 outside then yes, the 5.56 would go farther. What we discovered, and this was supported by the sate AG's office as well, within most interiors the 9mm was penetrating more than the .223/5.56.


Now me personally, I have handguns for home defense, but my go to is a pistol caliber carbine, a HK USC. It's loaded with Federal 230 grain Hydroshoks.

My 5.56 load is 55 grain soft points made for varmint hunting. No worries about overpenetration with those.
But that's for exterior home defense, not for indoor home defense. For indoors I have a 45 ACP Hi-Point carbine loaded with 230 grain XTPs.

Jake and I shot one round of 5.56 at our backyard backstop. It went through a 4x4 post, a pine tree, and took off through the scrub to parts unknown. And it was a hollowpoint. Just sayin...

Never said they wouldn't penetrate. Just the odds were better than a 9 coming out of carbine.
Also, I forgot to add, I don't believe frangible was designed for self defense. More for using in indoor ranges and/or on steel. Also, lead free.

Hollowpoints need soft tissue to expand. I had a Sierra 165 gr hollow point boat tail go through a tree and kill a deer on the other side of the tree. The deer was moving and stepped behind the tree trunk just as I pulled the trigger. I centered the tree trunk and the bullet went straight through and then flew true another 20 yards before hitting the deer. I found the bullet hole. A soft point would have expanded inside the tree and disintegrated.

I do currently use 9mm Hydrashok JHPs for my EDC pistol (P365). And they will still stay in the HD plan. I'm just wanting to add one of my AR's to that plan. I live in a small 1130 Sq ft. 3bd/2br with block & stucco outer walls. And my neighbors' houses are less than 20ft. away from mine. I'm a lot worried about penetration and would prefer frangible for 5.56.

I'll check them out but I think, in the end, I'll go with some kind of frangible 5.56.


Thanks all!

I’m glad you were able to get the AR to 100%. Now that you have experience building and troubleshooting this platform, your second one will be as easy as on his first date.

Bad Omen....

A light touch with focus on the trigger finger is all that’s needed. Your shoulder and either bag or bipod will hold the gun steady.

It's more my left eye than the hand. I'm right handed, but left eye dominant. I'm actually zeroed-in at 100 yards, even using the left eye. But I have much more practice to do. I think more so with controlling the rear bag sufficiently so that the scope lands where it needs to. Once I get that down, I'll pop for the 2nd Long Range course at JTAC.

No sweat. But thanks anyway. I'm just going to have to remember everything I've learned. I'll probably start the 2nd build in early February.
