Did Remington make a .30 cal 150gr corelokt psp bullet without the cannelure? Thanks for any info. Terrill.

These were discontinued many years ago , been looking everywhere for these , hope someones got some squirreled away and no longer loads them, thanks
I also posted this in the wanted forum, but thought I might have a better chance of finding them here
As far as the cannelure, like sap said just iqnore it. If you are working up a hunting load I would always crimp my rounds. Hunting rounds take a fair amount of abuse. I like that bullet crimped into place.
No, Remington never did produce, as a normal model, a PSP Core-lokt bullet that didn't have a cannelure. They were all supposed to have cannelures.
However, from time to time, bullets have things done or not done to them that are/are not supposed to be done. i.e. cannelures not added when they should have been. Every major producer of bullets has had this happen. When it does the bullets are usually sold as seconds as it takes more time and money to re-do/smelt them down and make them right. I have Nosler Accubonds and BT's with cannelures and Hornady 55 gr. .224" FMJ's without. Those are all seconds. So, if you've seen them that way, that is probably why. They would be seconds.
I'm not a bullet maker but I would assume that you would have to stamp in the cannelure before you filled the jacket with the lead core. Lead would be too soft and not provide a hard enough backing for the cannelure to be swaged in. On the other hand, I understand that is how Nosler "locks" it's partitions together is by swaging after the cores and jackets have been joined. Like I said though, I'm not a bullet maker and each type of bullet may have it's own peculiarities to manufacture.

Just a bit of info for you: Nosler uses two types of crimping grooves; one is called a rolled cannelure, which is where the completed bullet is dropped between a set of rollers and what is called a tooth segment, this actually indents the "rolled cannelure into the bullet. The other type is known as a cut cannelure; this is where a blade actually removes copper from a pre-determined point on the bullet and cuts a groove. Both of these processes are the final step in the manufacturing of the bullet, other than what is known as "tumbling which is purely for cosmetic appearance. Hope this helps.
Thank you for that information. I have always heard the Partitions were cannelured after the core and jacket had been joined. My experience with metalurgy is with aviation and we don't normally use something as soft as the copper and lead core compound. What makes sense to me in one application certainly doesn't in another. I would think then that the machines used to roll or cut the cannelures have a control method to ensure accuracy as the end result. I've been very happy with Remington and especially Nosler for accuracy. It would be very interesting to see these machines in action some day, if I ever get the chance.
