Podcast Outline:
Difference Between the 556 NATO and .223 Remington
- 556 Case Mouth Conducer 55,000 PSI; but SAAMI says it’s closer to 60,000 PSI
- .223 Copper Units or Measure (CUM) or called Mid Case Transducer, SAAMI says the max 55,000 PSI
- SAAMI Spec vs NATO Spec Chamber
- Chamber the same except the throat or lead
- .223 is 0.085”
- 56 is 0.162”
- Cartridge Difference
- Interchangeability (you can shoot .223 and 5.56 in a 5.56 NATO chamber, but not the other way around. Buy a 5.56 chambered gun)
- Chamber the same except the throat or lead
Ammo I’ve Used
- 556 NATO 62gr Green Tips (M855)
- 556 NATO 55gr FMJ (M193)
Military Moving
- M855A1
- Marines stuck on M855
- But using MK318 Mod 2 in combat
- Rumors of 75 or 77gr long range bullets
- Change is coming
For Home Defense
- Trusted 55gr FMJ
- Ballistic Performance
- Everything else you give up performance in tissue to gain other things
- Ammo companies and what they will give us
Considerations
- Do you need barrier penetration?
- Length of Barrel
- Creates different velocities
- Different Velocities mean different yaw and shatter points
- Shatter is what gets you desired effect
- Has to being going fast enough
- About
- 2600 FPS or above to get shatter
- 16” 2800 FPS at muzzle
- 20” 3000 FPS at muzzle
- From Ballistics by the inch
- 18” 2983
- 16” 2943
- 14” 2878
- 12” 2616
- 10” 2380
- Anything with a shorter barrel needs a different kind of ammo
- Consider Hornady TAP
- With short barrels and 55 gr bullets not much more then a 9mm
- Consider the longest shot you may take
- Wall Penetration
- If you go extra heavy barrel twist matter
