And for an example of spalling, I ran across this page [1] (warning: bloody) whilst looking up information on the .25 ACP handgun cartridge. It has a CT scan of an injured chap's skull; he had been shot in the head with a .25 bullet which failed to penetrate, but the bullet caused spalling on the inside surface of his skull. Doesn't say whether he died, but it must have been a life-changing injury. -Ashley Pomeroy 18:59, 20 August 2005 (UTC)

I read somewhere that the British army uses HESH shells because HEAT shells are less effective when fired from a rifled gun ( the spinning disspates the HEAT effect ). Anyone confirm this? Another question is there a velocity limit for HEAT shells : they must explose at the correct distance from the surface which would be difficult to achieve at very high velocities? 145.253.108.22 11:21, 22 January 2007 (UTC)

It isn't the HEAT that's less effective, tanks with smoothbore weapons use HEAT It's the APFSDS that less effective because spinning the round inside the barrel reduces the the muzzle velocity and hence effectiveness of the APFSDS. Anon 003 20:22, 7 July 2007 (UTC)

Actually HEAT penetration is degraded by spin - so much so that the french designed a 105mm HEAT round that had the charge mounted on a ball race within the projectile body - the shell was spin stabilised but the charge rotated at a much lower rate (the OBUS-G, round) —Preceding unsigned comment added by 90.217.231.2 (talk) 17:57, 10 January 2010 (UTC)
