223 Remington and 5.56x45mm NATO the Same Round? The only thing that some people confuse is by calling all cartridges “bullets,” as the bullet is only the projectile at the end of the cartridge. A cartridge consists of the bullet casing, the primer, gunpowder, and the bullet. While some people think ammo cartridges and rounds are different, they are actually two terms for the same thing.

Loading 125 nosler BTs at 100% case fill at starting velocity of 1940 at 14.5 grains vs h110 getting 1975 at 16 grains and only at 80% capacity. You can't fit enough in the case to get top velocities in lightweight supers. N110 has fill issues vs something like 300mp or h110. To slow and can't fit enough in the case. carbine or unsupressed.įrom VV page n120 it can cycle 150 grain - 200 grain subs. H110 Moreso if you do not need the extra gas to cycle say. I'm thinking both of these powders really shine as subsonic powders. N120 provides a better case fill for subs. Just from loading it, I liken it more to a1680 vs n110 which is closer to h110. Watch from about the 5min mark to about 7min to be mind some n120 out to the range yesterday. Keep in mind that db is logarithmic so small changes in dbs is a substantial change in actual noise. You've also likely noticed there is a substantial difference in the sound between "subsonic" 22lr ammo (which is 900fps) vs "standard velocity" (which is still subsonic in velocity).Įdit: Check out this curve. Velocity curve and you'll see after 900fps there is a pretty dramatic increase in dbs as the bullet increases speed.
300 blackout subsonic speed crack#
In other words, the air accelerates at the surface of the bullet as the bullet pushes the air out of the way, which creates supersonic fluid flow, which creates a supersonic crack that makes the makes the bullet still really loud. Long story short, a subsonic bullet can still create a supersonic pop because the air around the bullet is increased above the speed of sound as the bullet cuts through the air.
I suggest running 900fps or less if you really want good subsonic performance. I'll take it.įor plinking at 40 or 50 cents a round, they work better and are cheaper than anything else I've tried. Some people knock VV for their price but 6300 loads per 8. Very little smoke, no unburnt powder at all, no flash, clean cases, not a bunch of residue left over like some factory loads I've shot. If I wanted high performance subsonic defensive ammo I would be loading a handful of Lehighs. I'm sure those numbers would come down had I hand weighed each charge but I'm looking for something I can pump out quick and cheap. Drop # averaged of 8 drops then verified at 1 and 5 of the 10 charges. These were all loaded with a LNL press with powder drop. I would guess case capacity was around 70-80% after bullet seating, and was causing the burn rate to fluctuate.
However with the High ES and SD numbers I'm going to reload a bunch at 9.0, 8.9 and 8.8 and try to reduce seating length to increase the efficiency of burn rate. Most accurate load for me was 9.0 and all stayed subsonic. For me at 50 yards, best load shot just under an inch with an ES (66) and SD(20.1) Powder charge of 8.9 was right at 1050 fps. The Mk262 clone loads failed but 300 blk sub loads with 190 grain noslers and VVn110 did much better.ġ90 grain data was spot on. In 223 with a 14.5" barrel getting 500+ below published data from nosler and Sierra. I was actually surprised with the HUGE difference in speed of published loads. So we went out today in the pouring rain and shot a few loads.
