most accurate subsonic 300 blackout load

Is the 300 Blackout just a new knickknack for tearing up targets at the range, or is it the better mousetrap we’ve been promised? “No one in the military uses it and neither should you.”.“It’s just a novelty cartridge that will fade away like the fad it is.”.“It’s good but not as good as other ammo-stick with what you’ve got.”.On the other hand, skeptics claim that 300 Blackout ammo is overrated, overpriced, and flat-out inferior to most other kinds of ammo you can shoot. The perfect all-rounder cartridge for plinking at the range, home defense, and huntingīest of all, it was designed from the ground up to work in America’s favorite rifle-the AR-15-with only a quick change of the barrel required to shoot it.“Hollywood” quiet when fired through a suppressor.More powerful, hard-hitting, and deadlier than 5.56/.223 (AR-15) ammo.If you’ve spent any time poking around online, you’ve likely heard it’s. The 300 Blackout has become one of the most popular rifle cartridges available. If you want a cartridge that’s nearly “Hollywood” quiet, but still powerful enough to excel at home defense, hunting, target practice, and combat, you want to try the 300 Blackout.When combined with a suppressor, 300 Blackout ammo can give you one of the most powerful, nearly silent rifles you can have.The 300 Blackout is a rifle cartridge that’s more powerful than 5.56/.223 (AR-15 ammo) when fired out of a barrel that’s less than 16 inches long and works reliably with both super- and subsonic ammo.If so, then you want to read my latest book– The Second Amendment Manifesto: What Every American Should Know about Their Constitutional Right to Own Guns. Oh well, back to square 1.Do you care about your Second Amendment rights? Do you want to know why the right to bear arms exists, why it’s worth protecting, and what you can do right now to save it? The scrap of paper I used is lost to time, though the entry where I was going to enter the charges in my book remains. In case you are wondering why I have not listed powder weights for the velocities in my excitement to make up the loads, I did not record the charges in my reloading book. Anyway, I'd love to hear your musings on this.

The 220 gr BTHPs locked the action on an empty mag with measured velocities of 772, 797, 866, 933, and 976 fps.ĭon't get me wrong, I'm glad that the firearm is cycling with the anemic loads, but it seems odd to me that the factory subs consistently cause malfunctions at higher velocity (and I would assume pressure) than the hand loaded ammunition. The 208 gr BTPHs locked the action back on an empty mag with measured velocities of 801, 872, 971, 1006, and 1065 fps. Ok, this is what I find odd, and maybe those more knowledgeable can 'splain me this. The last shot of this string clocked at 1060 on my magnetospeed and did not lock the action back on the empty magazine. The max was 1061, min was 1029, SD was 14 with an ES of 32 fps. I still had the hornady black so I used that as a baseline for speed testing. Hornady black and the remington 220gr OTM subsonic both failed to lock on an empty mag.įast forward a few weeks and I have a 5x5 load test for hornady 208 and 220 gr BTHPs using Accurate 1680 powder. Everything but the Hornady black 208gr Amax subsonic cycled fine (2 of 5 short-stroked and did not pick up the next round). But before that, I took several factory offerings (subs and supers) and ran them through the gun just for function check. Ok, so I have a newish 300 blackout build that I loaded up some subsonic loads for.
