Subsonic ammo is heavier and slower moving but is very quiet. These loads are designed for long-range shooting and suppressed hunting at extended ranges. Supersonic loads are fast-moving and hard-hitting. These bullets are heavier than supersonics (270 – 350 grains on average) and generally expand larger to maintain good terminal performance.

Subsonics: This ammunition travels slower than the sound barrier (generally less than 1050 fps depending on altitude and weather conditions), making them quieter when shot suppressed and eliminating the supersonic crack.

The common weight range for supersonic 8.6 blackout bullets is 160-225 grains. This makes 8.6 blackout supersonic ammo perfect for long-range shooting due to their flat shooting characteristics and ability to maintain energy well downrange because they have higher velocities. Long grooves in its gilding metal jacket. The Sub-X bullet used in Subsonic Rifle features a lead core. Subsonic Handgun utilizes tried-and-true XTP bullets that expand reliably at subsonic velocities.

Supersonics: These loads travel at speeds greater than the sound barrier - over 1125 fps under normal atmospheric conditions at sea-level. Hornady Subsonic Ammunition designed for accuracy and performance below the speed of sound now comes in both rifle and handgun loads.

The FRP is a little loud but after that not bad.8.6 Blackout ammunition can be broken down into two main categories: supersonic and subsonic. Maybe more rounds of each so that FRP is gone and have someone listen. Let me go shoot some with the lil gun real quick.well could not really tell if one was louder then the other. Much loader to me with my can then the 7.2 grains of lill gun which got the same velocity as well. Just loaded up some 235's with 10.2 g CFE black Got avg 850 out of a 10 inch barrel.

Plus what are you sizing too? Check the chrony, did I say that already? The Sig 205-grain subsonic 300 Blackout ammo is Sig’s third foray into.

It’s a jacketed, lead-core projectile is engineered to reach full expansion at these mild velocities, thanks in part to its polymer tip. Yes I have a daughter that I read to every night, she's a Senior right now. The Sig 205-grain subsonic 300 Blackout has the stuff to stay quiet, moving at 1,000 fps at the muzzle of a 16-inch barreled rifle. So, do I start reducing loads until I get to 1050 fps, or did I miss something? I have 4227, CFE BLK, Unique, 2400, Accur#5, H4895 and Varget.Īs Miss Clavel says 'something is not right'. The load data that I had used was supposedly for sub-sonic. I had also loaded some Sierra Match kings 230 with 11.5 CFE BLK and they screamed at 1610 fps. I started with 10.3 CFE BLK 1547 fps ave! I knew the rest of my loads would be too hot. 300 AAC loads drove me to do more research.

So if the load works for you I’d stick with it, one of the things about hand loading is you can try different things and find they will work for your gun.Ĭheck out my website Just viewed you website, joined, but still don't understand the burn rate chart. However you also find the faster burning powders don’t typically produce enough gas to reliably cycle an AR. The reason you were quieter with the H110/Win 296 is because it is a faster burning powder, and it likely had much less energy left at the muzzle, then the much slower burning 1680. If it’s a bolt gun, then he might use a powder that gets the velocity, without needing to worry about fueling a gas system.Ī commercial ammo maker has to make a subsonic round that will absolutely cycle the rifle so they will load as hot as they can, but still keep the bullet velocity below 1100fps. So a handload with 1680 might be quieter and subsonic if the guy loading the road has a 16in barrel and he’s loading it so it just barely cycles his firearm. It depends on how much energy is left in the powder at the muzzle. The problem is “Quiet” is more then just a function of powder.
