Good vid OP! Have you ever tested 125gr Hornady from that setup? My daughter an I "tested" it on two does (yummy) in 2013, just would like to see how it does in gel. I haven't, but I'll keep an eye out for it. |

I'm having a hard time seeing why folks crap all over the round...the only down side I see is cost, but if you catch a sale, it's not all THAT bad. Let's not ignore the opportunity cost of doing that work. Which is substantial, since this is Arfcom and everyone hear makes at least $750 an hour. The opportunity cost isn't what his rate is, it's what he could have been making during the time he was loading. If he had no ability to make money during that time then his opportunity cost was, in fact, $0.00. |

Yup! To me, .300blk has a few advantages with certain ammo. The 110gr Barnes Blacktips offer full expansion, and solid expansion out to 300+ yards out of a short barrel. And it's barrier blind to boot. That's what makes it worthwhile to me. |

Energy isn't the best indicator terminal performance. You can have two rounds with identical KE, one will be devastating and the other pretty minimal. Velocity is pretty important for temporary cavitation. The 300BLK in the video above has a somewhat marginal velocity. The 5.56 50gr is going ~2650 FPS. Out of 8" barrels, they're both short range (100 yard or so) guns, really. Expansion is just a more reliable method of getting good temporary cavity effects than yaw. As mentioned above, the TSX rounds for 300blk are great as well.  Quote HistoryQuoted:

How's that compared to a similar 300blk round? and..at distance? (at work, or I'd look it up) 556 loses huge muzzle energy at 8", and considerable velocity. Effective range would have to suffer greatly. Energy isn't the best indicator terminal performance. You can have two rounds with identical KE, one will be devastating and the other pretty minimal.

From what I have read (I don't reload...so kinda iffy on this topic), 300blk uses magnum pistol powder (which makes the 357 mag comparison above interesting). Faster burning powder would give better results in a short barrel than slower burning rifle powder. |

.300 BLK does fall short of the velocity that 7.62x39mm can produce, but not by a lot. It seems to shine at about 110 gr, whereas 7.62x39mm really struts at about 125 gr. Does 7.62X39 do as well out of an 8" barrel? I'm sure someone has done the testing.

I think it's the opposite. Your numbers above have a 125 gr bullet from 8" barrel hitting at 1,963 fps. I'd guess 2.5" would be at *least* a couple hundred ft/s from ballistic tables I've seen, so that puts the 300blk fired bullet at same (or higher?) velocity as 762x39, but at slightly higher weight. |

I've debated buying them....do you have a review? You talking about the black rounds from Noveske, right? Quote HistoryQuoted:
Quoted:
That's why I use 110 varmageddon for my plinking round in 300blk. I can reload them for around 30 cents a round and they still give me good performance if needed. I use the barnes 110 for hd/hunting and have used hornady 125 sst in the past to take deer. I just loaded up a bunch of 125 nosler bts and a few 125 speer tnt, which both look promising out of a 9 inch barrel. I've debated buying them....do you have a review? You talking about the black rounds from Noveske, right? Yeah, it's the same bullet but I buy the normal 110 varmageddon (not the black ones) and load them with h110. The only thing I have tested the round on was a lvl 3 vest at 85 yards from a 16 inch barrel. It punched the first panel and ended up in several pieces and stuck about half way through the second panel. I think I was getting about 2370fps from my 16 inch gun and around 2145fps from my 9 inch gun. I'll try to find my data later. I have no doubt it would ruin a bad guys day within hd distances. There are people who use them on deer and they do well. I use the barnes bullet for deer just because I don't want a bunch of lead in my meat.  " />
I was able to cut out 106.3 grains worth of bullet from the vest. |
