Quote HistoryOriginally Posted By jwlaxton: I've seen a lot of people post about N110 for subsonic 300 blackout. I've never used it. For those that have used it and H110, I have a couple of questions. First is whether it gives you more or less gas than H110. The reason for the question is related to reliable cycling of the action. If your rifle is marginal with H110, will it be better or worse with N110, assuming you load it to the same MV with the same bullet? The second is related to it's bulk. Does it fill the case more or less than H110 to get an equivalent MV with the same bullet? The reason I ask is more to do with MV extreme spread than any other reason. I usually find that seating the bullet closer to the powder, if not sitting on it, gives me lower velocity spreads. Will the velocity spread get better or worse with N110? In my experience, H110 will give you more gas, but will be slightly louder. N110 is bulkier than H110. |

125gr TNT's over 18gr H110 at 2.075 function well in my 7.5" Faxon Gunner barrel. 4:30 ish when unsuppressed and 2:30/3 ish with a YHM Resonator K on. POI at 50 yards is within an inch on my factory Barnes 120gr JHP that are currently in my mags for HD. Going to roll a bunch of these now!

STARLINE brass ? I bought some at my reloading store yesterday Thought I read they had less case capacity ? Anyone use it ? Anyone have a pet load using H110 & 110 VMAX ? Thanks |

I bought a bunch of Starline brass.
Starline is HEAVIER than Lake City or Winchester Some of the Starline is on second firing now. I haven't adjusted my load data for it. I suck at measuring water capacity. So I quit even attempting it. Maybe WEIGHT of the case means something. I don't know.  Attached File Attached File Attached File |

The brass has never been fired, and is from a primed and ready to load batch weighing 85.4gr to 85.8gr without the primer. I guess there is a lot of variation in 300 blackout brass, even with the same headstamp.  |

I don't have time or desire to get into casting. Is there an accepted best/cheapest powder coated cast lead 220gr or similar weight shaped projectile for subsonic use?
Blue Bullets has one but its boat tailed and I've been told that can create melted lead and make a mess of sealed rifle suppressors, any credence to that? |

First time loading 300 BLK. Worked up a subsonic load for my RAR bolt gun. Not a lot of info out there on AA #9, but another user here had decent results.
Barnes range pick up brass 190gr Sub-X AA #9 COL 2.080" Federal 205M primer 8.4gr Avg 1070 ES 17 SD 7.4 8.2gr Avg 1032 ES 15 SD 5.5 8.0gr Avg 985 ES 42 SD 15.1 Here is the 8.0gr 50 yard group  Here is the 8.2gr 50 yard group  The "Un" was an unsuppressed round I shot first to ensure no keyholing or projectiles coming apart before putting the Surge on. Really happy with the results. Going to load up a couple hundred of the 8.2gr for quiet back yard coyote and armadillo hunting. |

I've annealed 5.56, and when annealing it using Tempilaq I know where to stop on the case to ensure that I'm not weakening / softening the lower portion of the case. When annealing 300 blackout - since its a shortened 5.56 case, how low on the case is safe for annealing? I definitely don't want to get into a bad situation.

I'm working on a subsonic load with Berry's 200 grain and 220 grain bullets and H110 powder. I'm using an 8" pistol-gas AR. Overall length of 2.230". At 9.4 grains my AR cycles it flawlessly with the suppressor but will not consistently feed without the suppressor. I figure I'm pretty close to the bottom of what will work at this powder charge.
There is a bit more port noise than factory subsonics. Is this because I'm using a less than optimum powder? Or could I lower my powder charge and reduce the noise? I also wonder if adding weight to the buffer could make it a bit quieter. |

So I've been search this forum as well as various other forums and the data I'm finding varies. I'm starting to load 300 blackout and have some questions on powder loads.
I have CFE BLK (I know may not be the best powder) but it's what I have for now. I have Berrys 220 gr bullets and I'm loading them at 2.172 O.A.L. crimped. My question is what should my starting powder drop be, I've seen some say 11 grains and some 12.2 etc. I want subsonic loads and I'm using a 9" BCM upper suppressed. I'm not hunting, just using it out at the range so looking for as much quietness as I can get. Not shooting anything over 100 yards either. I appreciate any and all input, I will be getting A1680 in the future after I burn through my CFE BLK powder. |

I you want the most quiet, get a Kali-Key bolt carrier.
Turns the gun into a single-shot without any other modification of the gun. Allows you to swap from semi-auto to single shot in less than 5 seconds. I have one. It works quite well. |

I actually have two of them Gen 1 and Gen 2; I'm mainly interested in load data for 300 blackout with CFE BLK and what others are loading in terms of # of grains for subsonic. I want to keep it semi auto :) |

You're probably good to start anywhere from 11-12 grains. Work down in small steps and pick a charge that cycles your rifle, stays subsonic, and is fast enough to stabilize the bullet. |

Anyone have a good starting point for Sinterfire 125s? I reached out to them and haven’t heard anything back yet. My plan was to just start using 168 data and go from there. I have a BA Hanson 8.3 1/7 and have H110, CFE BLK, and 1680 on hand.

Going thru my reloading stuff and found about 1000 125 gr. Sierra Pro Hunter projectiles, a jar of Trail Boss and more than enough primed cases. I also found the specs for loading with those components, and I think I got all stuff in anticipation of loading for my 300blk bolt gun...which I have sold. 7 gr or so for subsonic with these.
So, I still have a 9" and a 16" AR, and an Omega 300 supressor that can be used on both. I'm not really after quiet, and really don't care if I used them suppressed or not...I just want to load up plinking ammo and go shoot it since I have it. And...in the AR's...it would be optimal if they would cycle in either (suppressod or not), but I just don't think they will. I really wouldn't mind if they would reliable NOT cycle, and just manually cycle after each shot? Does anyone know what results I'd get with the above load either with or without the suppressor on the 9 or 16 inch barreled AR's? Thanks! If they are going to be unreliable (stovepipe, partial eject, etc.) I'll just use my H110 and make them all supers and still shoot them up. Would rather have slower closer rounds for steel. |

Grab some 4227 for plinking instead of burning up the H110. It's cheap and will make decent velocity supers that are reliable and pretty quiet. |

In my opinion, the ABSOLUTE BEST bullet for running slow as you dare in .30 caliber is the chunky 200-grain, purpose-built-for-subsonic LAPUA. Price is usually 50 cents each.
Lots of bearing surface for stability, and consistent velocity. I’ve been dissatisfied with the wide variation in velocity I’ve experienced with heavy .30 caliber “match” type bullets at velocity low enough to prevent all “cracking.” Which is usually 900 fps. Getting only just-below the “textbook” speed of sound isn’t good enough to make the gun 100% crack-free. I suspect the sometimes odd-sounding crack heard at 975-1050 fps is actually supersonic bits of gunpowder spewing at the muzzle as the subsonic-velocity bullet exits. Below 900 fps gets you true “click,… WHOP” sound effects in suppressed 300BLK. Above 900 fps gets more of a “Psshaak,… WHOP” sound on most shots. |
