GAHUNTERPartitions with Cannelure?
Where can I get .308, 180-grain partitions with a cannelure? I tried all the uusual suspects (Grafs, Midway, Huntington, etc.)with no luck.

adamhunterSeems like I read on Nosler's site or in their manual that they only make those for ammo companies that load their bullets and said since handloaders tend to experiment with different seating depths, why have a cannelure?
30+ years experience tells me that perfection hit at .264. Others are adequate but anything before or after is wishful thinking.

Antelope SniperThey are called "Seconds".
Sometimes you can get them here:

impala#03Hornaday used to make a tool to cut a cannelure anywhere on a bullet. May still be in their catalog.

I don't know which Nosler Partitions currently have cannelures, but a a few years ago 308 and 338 did not have canncelures, but 375 and 416s did.
You might look into using the Lee factory crimp die as it allows you to crimp without a cannelure.

Hey, Steve, you beat me to the 64-dollar question! A cannelure, particularly one applied after the manufacture of the bullet, is a great way to potentially degrade accuracy. The only purpose a cannelure serves is to make a place for a mouth crimp. Again, crimping is a great way to degrade accuracy and is unnecessary except in very limited instances with certain cartridges and actions.

vapodogA cannelure can act as an assist to holding the lead core inside the jacket if the cannelure is pressed into the jacket.
Many of Hornady's bullets are cannelured this way and frankly, I've not noticed a loss of accuracy!.....at least of consequence!

That's true. And too, some of the most accurate bullets I have EVER had was some bulk Hornady 55gr bullets that I bought to Pdog shoot with and they had a channelure.

To hold the bullets at the loaded seating depth.
A 338 will "help" seat your bullets further due to recoil. Ask me how I know . . .

I am a big, big fan of the Remminton .30 180 grain Cor-loct that has the pressed in cannelure(at 2700fps). The are cheap and accurate and have killed everything I have ever shot with them, and it has only taken one shot. "The deadliest mushroom in the woods" is not just a cheap advertising slogan....
And as far as a cannelure degrading accuracy, I don't doubt it one bit, but 99% of the time you won't notice it in a hunting rifle.
