- Bullets With Cannelure | Without Cannelure - Snipers Hide
A cannelure is there so you can crimp the case mouth into the jacket thereby creating a mechanical lock which helps with ignition and bullet setback Unfortunately a cannelure harms accuracy and that is why match bullets don’t have cannelures

Re: 77 SMK cannelure or not?? Sierra came out with the cannelure so they could be compliant with spec changes to the Mk 262 ammo They had the contract, lost it to Nosler when the spec changed to w cannelure, now came out with their cannelure option and won the contract back If you wanna be "spec", get the cannelure
- Seating a Bullet With a Cannelure | Snipers Hide Forum

Cannelure Yes if it's defensive ammo with out a question I'd crimp and use a cannelure bullet I've seen and had My own noncannelure bullets back up into the case on many occasions and causing a compressed charge situation and if I didn't down load My plinking rounds it could have been ugly
- Noob question. Do I seat the bullet to the COAL or to the cannelure?
