Throw a 1 oz ball bearing at the tank at 50,000 mph, it penetrates the armour and kills the occupants. The material the projectile is made from certainly helps, but speed is required to defeat armour. Actually, rather wrong. The shape of the charge is what's most important in anti-tank ammunition. It's specifically designed to penetrate that armour. If you just hit it harder with a 'normal' projectile, the reactive armour just does it's job better. Obviously you'll reach a kinetic energy where a projectile will penetrate, no matter the armour properties, but those are way beyond 'normal' battlefield weaponry. Google 'shaped charge' to get a really good explanation Quote Link to comment Share on other sites More sharing options...

Not all MBTs or IFVs have reactive armour, and not all anti armour rounds are based around shaped charges. Quote Link to comment Share on other sites More sharing options...

Modern body armour is rendering the smaller calibers obsolete. Russia went from the 7.62mm AK-47 round to the AK74 5.45mm round and they too are looking for a new better round The new 6.8mm round can fly twice as far and penetrate all modern body armour. The current NATO round needs special tungsten carbide core bullets do do this. Not mass produced so costly. Looking online at the offerings of 6.8 SPC, 6.8 Grendel and 6.5 creedmore the creedmore is a better round. But the Swedes had it sorted years ago with the 6.5 x 55 for the Mauser!

They redesigned a round the public .could own and it's a much better round. Military are certainly one for keeping some outdated gear on the go. The .460 Barrett? I seem to remember hearing Barrett developed the round to bypass California state laws on .50 calibre guns. Quote Link to comment Share on other sites More sharing options...

Lloyd90 Posted November 23, 2019 Report Share Posted November 23, 2019 Are they adopting it then? When can we expect cheap ammo to filter through for hunting? Lol Quote Link to comment Share on other sites More sharing options...
