pianoman 3,587 Posted January 31, 2016 Report Share Posted January 31, 2016 (edited) The grooves, turns, rifling lands call them what you like, are there to simply impart spin to the round and provide gyroscopic stability in flight. The greater the precision in the way the lands are cut, the more accurate the bullet or pellet fired from that barrel will perform. This is why headsizes of air rifle pellets are so important to get right and maximise the accuracy from the barrel of your rifle. The lands or rifling are the fingerprint of the rifle as no two barrels are ever identicle in a particular make/model and calibre. There are always microscopic differences. And it is these differences that police forensic laboratories are equipped to find and determine whether a particular weapon of a particular calibre was used or not, from among any number of identicle weapons tested. The utter bloody rubbish you hear from people who claim to have something of an interest in things like this, are a constant source of amazement to me!

Deker 3,478 Posted February 1, 2016 Report Share Posted February 1, 2016 The grooves are rifling to impart twist to the bullet and give it stability in flight. In theory the grooves on a bullet could be matched to the rifling on a particular gun if the bullet wasn't smashed or squashed on impact - which they are. Unless of course Gil Grissom from CSI has a way of unsquashing the bullet for examination. In answer to your mate - No it's not there to match the bullet to the gun and Yes, he is a bellend. And that's about the size of it, but a quick rider, the crown may well be more of a give away forensically, if it shows any damage patterns or cutting inaccuracies, otherwise the rifling will be the main source of evidence!
