I've heard a lot about 75gr Hornady TAP but I've also read that lighter rounds should be used in shorter barrels. If it helps, I have a 10.5" barrel. What are you guys using?

Hornady Critical Duty 40s&w 175gr!

Look into Hornady 75gr BTHP. That and Hornady 60gr TAP Urban are specifically engineered to perform well in the 10.5" barrel.  Walmart sells 60gr PDX-1 Split core that performs well but it is very expensive. Just remember, shorter barrels produce less recoil therefore you need a bullet that is designed to expand instead of fragment under pressure (ie standard 556 green tip FMJ).

Barnes makes a good 55gr TSX bullet that does well in shorter barrels with higher twist ratios.

With the 223/556 bullet, you are more concerned about shot placement than expansion. Get good at shooting accurately at SD ranges and be ready to follow up with multiple rounds.

For my 10.5, I use the same defensive ammo as my other AR's - 62gr Federal Fusion.  It has a low enough expansion threshold to still be effective out of the shorter barrel, but 10.5 is about as low as I would go with it.

HST's and shitloads of them.

Fed Fusion / TAP/ and shitloads of them.

Quantity has a quality all of its own.

I think people tend to over think these things. With a handgun (not talking about an AR pistol here), a premium hollow point is ideal as it offers a little something to overcome the general lack of power that is inherent with almost all popular self defense calibers.
 When we start talking about rifles... The power factor is waaaay up there in comparison to a handgun. I wouldn't necessarily advocate the use of green tip within the confines of a family home, BUT..... It most certainly will do the trick. There won't be any home invaders shrugging off 5.56 rounds of any variety.

I run HST in my handgun but it sounds like I should be looking at 50-60gr rounds for a 10.5" AR pistol and 75gr for regular 16" barrel.

Federal HST (.45ACP) in Glock 30S (Main Carry and or Home D)
1 30 rnd magazine of Federal Fusion in AR15 (20" that's basically a A2 but with flat top upper) with all the rest loaded with M193 (Home D & SHTF)
LCP with Lehigh Defense 90gr Xtreme Penetrator (Deep carry / backup)

Everything else stays loaded as well, with the best ammo I have, but isn't ideal, or I have something better for the purpose.

Another vote for Federal Fusion 62gr. It seems to be the most accurate in all of my ARs from 16in down to 7.5 barrels.

I keep my 9mm M&P Pro loaded on my nightstand at night loaded with Hornady 135gr Critical Duty.  Id trust my life to this gun.  Accurate, reliable and easy to shoot.

For my AR, I keep one mag in my cabinet loaded as such.  First 15 rounds are Federal 55gr frangible.  I dont need to be shooting thru walls in the house.  Over penetration is bad.  And if you dont think that a frangible bullet would be effective, go check out videos of ballistics gelatin tests.  Generally 6-8" of penetration, and a very nasty dirty wound cavity.  The only down side I guess is if they are wearing armor...    The second 15, does it really matter?  55gr FMJBT's are what I have an abundance of.  If I had them on hand, Id load some Vmax's or GMX's.

My choices for ammo from a 7.5 inch barrel are as follows (and have been tested and proven)

1. MK318
2, DRT 79g
3. Federal 45g HP
4. Hornady TAP 55g
5. Winchester Ranger SP 55g

These are the best performers

I have found that NONE of the TSX rounds perform from a 7.5 inch barrel.  I have tried 55 and 70 grain, both acted like a FMJ, no expansion or fragmentation.  
I love the TSX in my M4 and it performs very well, just not for the short barrel.

Federal RXM556T3.

It is a 62gr softpoint and give over 2700 FPS out of a 10.5" bbl.
That is pretty zippy.
I believe it was created by/for the FBI for 10.5 inch barrels.

In what did that expand, water? I only got partial expansion from 50gr TSX in 10% ballistics gel @2400fps at 15yds and 50yds out of my 7.5"




Had to go down to 45gr TSX and 2550fps for full expansion in 10%gel.

Patrick Sweeney had an article in G&A recently where he cut a 24" barrel down to 7," inch by inch, and tested a bunch of different brands and weights.  He believes you need at least 2300 fps for reliable expansion.  Out of a 7" barrel, only Hornady 35 gr NTX and Winchester 35 gr Silvertip go that fast.  Add an inch and you have a lot of options.

Care to explain?  While it may not be the ideal round for that barrel it will still penetrate nicely and that loud BOOM and flash will likely stun the intruder as well (thinking typical thug here).  From what I have seen it will "do the job" pretty well.

Ain't that the truth. I have some 53gr tsx loaded up and some mk318 but will use anything in the 223 that I have avail. Some work better than the others but for the most part, all will work well enough.

TAP in the house, but switch over to a 2:1 m855 to m856 mag when in the vehicle.  Thinking it has better windshield penetration and it's nice to see where the rounds are going as well when dark.

Agreed. I think folks discounting the use of these varmint rounds in the house are really over thinking home break in situations. You're not going to get into a protracted firefight and have to blast through walls.
