    Federal 55 or 62gr tactical bonded (xm556fbi, le223t3 etc).
    I don't care for the low velocities i have seen from gold dots.
    The hornady sbr is slow (it is a 75grainer) but suppresses well.
    Loadings with the barnes tsx rounds are great too.

    Any Gold Dot is fine. Widely used in LE.

    I stocked up in Gold Dots when PSA had a sale, but not sure why. 193 is all I ever shoot out of my 5.56 ARs. Hope to never shoot anything other than paper, cardboard or cans, though I have faith in 193 if the unthinkable happens.

    Like syntaxerrorsix I am firmly a fan of XM 193. Shoots well in rifles and carbines, and poi is pretty much same as 55 grain fusion & assorted soft point rounds.

    Ah yes, the Hornady Mozambique. Excellent choice.

    In all seriousness, the heavier the better for a short barrel. I don't own a single weapon in .223/5.56, so have no idea what to recommend, but do know physics. For a short barrel, the more time it has to adequately burn the powder is dependent on resistance, and that resistance is provided by mass, being the weight of the projectile it is expelling. I see folks talking about 62 grain 5.56 all the time, if there is anything heavier, would suggest it.

    I have a 3" barrel 9mm as one of my carry guns, and all I load it with are 148 grain hollow point projectiles. Give the ammunition time to do it's job, the more foot pounds the better. While a fireball is impressive, all it represents is lost energy, as it happens after the projectile has cleared the barrel.

    I would suggest seriously rethinking that strategy, at least where 9mm is concerned.

    C'mon man that isn't "physics." I wish it were. Then I could stop testing and stop buying inferior bullets and stop participating in the raging and neverending debate across the interwebs on the topic.

    People talk about 62gr (and 55gr) all the time because it's viable. In many cases better than heavier rounds. Speed drops off tremendously in shorter barrel. The "physics" and ballistic charts and personal testing tells me that getting the speed up is more important than shoving the heaviest round in there that the barrel will fire. Granted, AINT A DAMN THING WRONG WITH RUNNING HEAVY. But if we're talking best in an SBR, I would recommend a soft point of some flavor (hard to go wrong with speer gold dots) in the order of 55, 62, 75gr.

    Non soft point rounds in 223/556 generally depend on high speed to fragment, which is not something abundant in shorter barrels, especially as it moves further down range.

    I don’t think twist rate matters for the 20ft shot down your bedroom hallway.

    I didn't see where the OP said he was confined to a bed and would never have a shot over 20 feet. Nor did I see this was only for interior residential structure purposes.

    Yeah - not a 5.56 ballistics guy - the 62 vs 75/77 info is what I'm looking for.

    I get heavier is better from short (An AK pistol w/ 7.62x39 bleeds way less energy from the shorter barrels than .223). I get that heavy also bleeds more energy farther.

    Not ruling out 100 yd plus shots here...just primarily 50 or less.

    I also get the soft point love - grew up shooting an assortment of calibers with them. Not 5.56 though...

    I have 64 grain Winchester Power Point loaded in my carbines. I also have 64 grain Gold Dots as well, but not looking for a bonded round in the home.

    Remington Core lock, 55 grain, similar to what most people shoot for practice, but a hunting bullet.

    Im really wondering if 62 vs 75/77 makes a difference from the 10"

    I have shot 62 from this and it worked fine. Am I giving up serious range by going to 75/77, or as good as 62 at 100yds or so...

    GD 75gn was made for short barrels. 62gn soft points are going to be great too. At 100 yards all those weights will hit hard with the right bullet. Gold Dot, OTM’s and such. In my opinion the best bang for the buck is Gold Dot and Fusion. Decent priced and arguably the best bullet. 55, 62 and 75
