AR15 advice

OK, so you have a ton of flash and unburnt powder. So the stuff isn't necessarily dirty, but it's not smart to practice with this stuff. So no, I will not buy this stuff or recommend it. Lots of premature wear from a +P (voids Glock and other maker's warranty). I only buy subsonic anyway and I suppose I will continue to do so.

I guess it shows that muzzle energy/velocity. It's basically equivalent to a 125gr load in terms of energy, with more flash. Some recoil reduction, but a 9mm is tame anyway. Why go with +p wear when it's got slightly less energy and far worse penetration?

Well, I would have thought the obvious answer is that it will penetrate Class III armor. You can take all the penetration of regular 115 grain +P 9 mil and throw it out the window if the target is wearing body armor, because you're going to get zero penetration.

I wonder about a home defense setup where you load your mags with a combination of Liberty and +P.
 
I don't get the Class III penetration if it has 1/3 the penetration in gelatin. I get the expansion, but I doubt the real-world utility. I am not too concerned about a Class III vest-wearer during a home invasion. I figure if he went to the trouble to wear the vest then a better target is a geriatric couple, SWF, etc. I also have mags full of SS-109.

I have steady hands and would go for a leg and head shot if the guy was obviously wearing. I mean, I suppose I am fucked if he breaches with an Abrams tank and M240 guns.

I run subsonic (suppressed); so I guess I am a sitting duck.

" ...My idea of an ideal home defense weapon (other than shotgun) is a 9mm carbine. I have two.

Dang, man... my same conclusion.

I'm liking the Hi-Point 995TS carbine. Accurate, shoots great, reliable, inexpensive. (I know... lots of gun enthusiasts poo-poo Hi-Point. They shouldn't.) Even with my old eyes and frazzled nerves, can still pepper a 6" target at 30 yards in off-hand. Few "home defense" situations would involve longer distance than that.

If one wants to go hi-power in a carbine... check out Henry's lever action .357/.44 Magnums.

Sure, go with the Hi-Point. You're not looking for a range-toy or an investment. I've never owned it, but have shot one plenty. A handful of stovepipes over the years. I wouldn't run +P, but make sure it's not running weak factory loads. Go with a Mossberg 500 if the goal is limited to home defense.

First let me preface by saying I am not an expert. Now I can disagree with you with impunity ;). J/K of course. I know very little about any of this. But, from what I can tell a 1/7 can spin a 55 grain 5.56 at ~300k, basically just short of tearing it apart. Then when it hits flesh, it tumbles.

Or so I have been told. I've tried to set up people to shoot to test this theory and it is kinda hard to make arrangements.

Interestingly, 7.62 ammo seems to be about the same price as 5.56 (or cheaper). That is surprising. Perhaps my theory of buying the popular weapon has a weakness in that suppliers are still unable to meet demand.

Yeah, you must be looking at AK74 ammo. 7.62x51 is 2x (NATO 5.56) the cost for equal quality. Understand that the sucker is traveling at close to the same velocity as 5.56, but a 50% larger diameter. It has nearly the terminal ballistics as the 30-06.
