I have a mini 14 and a case of pmc 55gr fmj for target shooting but I'm wondering what would be best for defensive use. I have picked up a few boxes of hornady vmax but was wondering what everyone else uses. Thanks
Not true.... Ballistics test at our range proved that Federal Bonded and Gold Dot Rifle rounds penetrated less than or about equal to our handgun ammo. The ammo still defeats barriers and soft body armor but the rounds are specifically designed to reduce the risk of over-penetration. You can get the data on the ATK LE page if you don't believe me.Hornady .223 TAP-FPD (aka TAP URBAN for .le/.gov) is a V-Max bullet.
For general home defense, I would recommend that you avoid using barrier or bonded bullets. The issue of over-penetration comes into play. A barrier round like a Federal Tactical Bonded SP, Speed Gold Dot, or Hornady TAP Barrier will have exceptional performance inside a human cavity, but it is likely to over-penetrate if it does not hit a sufficient amount of resistance with body mass or bone. These rounds are designed to defeat barriers like metal, glass, construction materials, and soft armor, and still have enough energy and velocity left to deliver lethal hits.
Ideal ammunition would be Hornday TAP-FPD in 55gr or 60gr, or in the 75gr BTHP TAP version. The 75gr version will have rapid expansion and fragmentation, but has a very low propensity for over-penetration. The heavier cartridge will also facilitate deeper penetration into the cavity. I would abstain from 40gr loads, as they tend to expand too rapidly before they can do severe lethal damage to vitals. The 60gr for the Urban/FPD loads is ideal for those bullets.
Other options include the Federal Tactical TRU in 55gr Hi-Shok SP or the 55gr Nosler Ballistic Tip or 50gr LOTM if you want a more rapid level of expansion.
Another option is hunting grade JHP loads or heavier polymer tip loads, like 55gr+.
I personally use Hornady TAP 75gr BTHP in home defense magazines (kept separate, loaded and readily accessible).
For work, I use 55gr Federal Tactical Bonded SP, but that is ammunition for shooting through windshields, car doors, residential and commercial windows, etc. Not stuff I'd like to use in my home.
I would recommend against FMJs. 55gr FMJs can over-penetrate if they do not expand correctly. FMJ ammunition is unpredictable in its behavior. You can make assumptions about what it MIGHT do, but not about what it WILL do. If you deal with someone that is thin, the bullet is likely to pass right through them due to insufficient amount of mass to cause deformation. If you go to the 62gr M855/SS109, you are really asking for trouble due to the steel penetrator.
Also- If you come across any Hornady 75gr V-Max, skip it. It won't fit in your magazine.
30 rounds of 60 grain V-max would leave a disgusting mess to clean of any organic creature human or not.
Are you talking about terminal performance upon hitting the body? Or are you referring to mid-flight/external ballistics? If you're talking about in-flight, it's likely an issue with twist rate. 75gr needs 1:8 or 1:7 to properly stabilize. I've used Hornady Match and Hornady TAP 75gr BTHP extensively out of a 1:8" barrel, and have had exceptional performance out of it.Merlin@45 said:I use 75 grain TAP. In a .223 with a 1in9 twist, I've heard it tends to "tumble" out beyond 75 yards or so. Not sure if that's true. But, as my Bushmaster Carbon 15 would be what I consider my CQB weapon, I wouldn't deploy it much farther out than that, anyway.
I didn't say it was a guarantee, but the concern is relevant and real. Human body mass plays a major role in how those rounds perform. Ballistic gelatin is a constant density and mass. The problem comes with factors like shot placement on the body, and size of the person you shoot. Additionally, the body composition of a person plays heavily into the issue. If you shoot someone that is very fat, or someone that is very muscular, barrier rounds will not overpenetrate. If you shoot someone that is very thin, or someone that isn't excessively overweight but is out of shape and basically just flabby (in the words of Hanz and Franz), then you have over-penetration risk. Lean mass is significantly more dense than fatty mass, so if you shoot someone with very low lean mass, the resistance is reduced. Someone with more lean mass will increase the resistance on the round and the penetration will be less.COLOSHOOTR said:Not true....
