Other than that, I’m leaning towards 300 Blackout as the better option. 300 Blackout vs. 5.56 Bullet Drop (In Inches) Range (Yards) Supersonic 115-grain 300 Blackout Subsonic 190-grain 300 Blackout 55-grain 5.56; 100: 3: 4: 2: 200: 8: 30: 4: 300: 24: 96: 12: 400: 54: 216: 32: 500: 108: 360: 60: Before we talk about the terminal ballistics of 300 Blackout, let’s look at how much 300 Blackout bullets slow down on their way to the target. M855A1 Or for reloading, even cast. That is a AAC 300 Blackout Handi Rifle and no bullet drop calculated as he emerged from the woods about sixty yards away. Sure, that isn’t the more-than-2,400 fps the .30-30 can allegedly do, but with the M&P15, you get a self-loading rifle of the same weight with easy optics mounting options and velocity that’s more than close enough.

Theoretically, the 300 Blackout has the performance to make it a threat at 500 yards, though it’s doubtful most will take it this distance. I want to start by saying terminal ballistics is very complicated. but, for the same caliber, more weight means longer projectile, and that requires a tighter twist rate. Do I get to claim versatility again? I don’t think 300 BLK replaces 5.56 NATO. We make a Pistol/SBR load which is optimized for barrels between 7-11” and a Carbine load which is optimized for 16” barrels.

The Top .300 Blackout Suppressors Analysis On the subsonic side, the first dot is good to 50 yards and the second dot is good out to 150 yards. I searched online but couldn't find it. There are a great many optics on the market today, but a few are ideal for 300 BLK rifles. From the military’s perspective, that’s ideal. And when I say “slightly” decreased energy, I’m talking within 50 ft/lbs at any distance, with the 5.56 actually outperforming 300 BLK at some. But, after looking at the numbers, AAC definitely succeeded in seamlessly putting 7.62×39 performance into a standard AR-15 platform. Member Joined Apr 2002; Posts 4583; EE 100% (327) NV, USA. Uhh… I think you might be confusing M855 with M855A1. 300BLKs military requirements was to be able to switch between subs and supers and suppressed and unsuppressed with a non adjustable gas block. Velocity (FPS) Energy (ft/lb) 2375. A rifle bullet going slow (under ~1800 fps is slow) is going to be significantly less effective.

This is especially true compared to the 5.56. 2232. The 5.56 had at least 500 FPS on the 300 Blackout for velocity, slightly decreased muzzle energy, a little less than half the bullet drop, and less wind drift. We’ve met, several times (both shows and writer events- we’ve ate, drank, and talked at length) and I genuinely like and respect you, but I’ve got to call a spade a spade: you’ve run this once-trusted blog into the ground by letting half-wits generate content. Reloading? Moving at almost twice the velocity, these bullets have the speed behind them to open up, and we all know speed helps combat bullet drop, thus giving you a little more range..300 BLK Alternate Options. The Discreet Ballistics 300 Blackout 190gr Subsonic Target Load is intended for use in semi-automatic and bolt action firearms chambered in 300 AAC Blackout. That’s quite a bit of variety…. 820. The disparity in the BCs makes me think that either Engel is underestimating their BC or Hornady is overestimating theirs. Maybe the most significant application of this is barrel twist rate. (NOTE: After reviewing comments from readers, the author sent us updated supersonic data, shown below). I’ll probably go through the trouble to get it suppressed. In terms of hit probability, the Blackout has an effective range of 460 meters. The 7.62×39 ammunition is basically identical to the 300 BLK ammunition. 1939.
