Adding A Cannelure To 357 Sig Jacketed Bullets...

[ArrowJ]

What are your thoughts and experiences of adding a cannelure to jacketed (or cast) 357 Sig bullets using the CH4D Cannelure Tool (or a similar tool)?

My two concerns are first accuracy, but given that a huge segment of bullets already have a cannelure and are not adversely affected in this regard for the given application, I will dismiss this, and second it would require headspacing on the shoulder which is something I have never done having loaded only straight wall cases in the past. I guess I would need to read up on rifle loading and apply those principles? Will everyone's dies allow this, or does die choice effect how the headspace can be controlled?

If done properly a canelure will affect nothig but BC.

But why?
357 SIG is a "light recoil" cartridge so bullet shift is none existent?
Youre not going to shoot 158-180grains bullets at 357Magnum velosities.

Actually I read about it at http://www.handguninfo.com/Archive/www.Pete-357.com/

It is an old web page from the early days of 357 Sig. He is talking about bullet setback.

I've added cannelures to about 4,000 9mm bullets for use in 357 Sig using my CH4D cannelure too. And I got a blister!

It works and does help in preventing bullet setback in this high pressure round. I've even cannelured Berry's plated bullets with good success, as long as I didn't go too deep with the cannelure.

I prefer to use a bullet with a cannelure for loading 357 Sig and I crimp into it. That's not the only thing keeping the bullet from setting back when feeding, since it also requires good neck tension and a powder that fills the case. I've settled on AA #9 for just about all my 357 Sig loading, since it fills the case and is extremely accurate.

Hope this helps.

I was looking at a list of low flash powders for 357 Sig and came up with AA#7, HS6, Universal Clays, and VVN305. Do any of those fill the case well?

You would have to look at the volumes required for the bullets you intend to use. I've had such good results with AA #9 I didn't look any further. I loaded up 14,000 rounds with AA #9 and every time I take my 357 Sig pistols to the range, I'm glad I used that powder.

Hope this helps.

I totally solve any potential issues with setback on my 357 Sigs by using a slight pinch with a Lee Factory Crimp die as the last operation. Tight as a whistle, and never a problem.

And, BLUE DOT fills the case wonderfully, and is the ONLY powder I would ever use for the 357 Sig.

I'm many tens of thousands of loads into building them.

I have the cannelure tool your asking about. I try my best not to use it for any volume production. I would lower my load or buy the correct bullets for the job.

Do any manufacturers actually sell a correct bullet with a cannelure specifically located for the 357sig? I have not run across any. Maybe I'm not looking in the right places.

Is the tool inferior or poorly designed in some way, or is the accuracy of your rounds poor after adding the cannelure?

It works well enough but takes forever. If your loading for pistols on a progressive and shooting much at all, you will grow tired of it taking nuch longer to process bullets than it takes you to load ammo.

If I am reading correctly you are thinking about fixing a problem you don't have, yet. Give your load/bullet a try first.

LOL. Well said.
