Cannelure not right for a cartridge

[Capt_Oscar]

In an interesting twist (reloading master class): if you use bullets that aren't designed for your cartridge. IE: Using 50-110 bullets for a 500Nitro Express. The cannelure doesn't line up for crimping. Additionally, the seater die is designed for a roll crimp for the cannelure vice a tapered crimp against the bullet bearing surface.
So, I'm checking loaded rounds to make sure they fit in the chamber of my 500 Nitro Express single shot (TC Encore) but the Woodleigh 500gr FP loaded ammo is NOT dropping in flush because the case mouth flare to seat the bullets isn't being taken out enough.
IF you take the guts out of your (straight wall cartridge) sizing die and back the die out about 6 full turns you have the makings of a taper crimp. You just start turning the die in 1/4 turn at a time until I got just a hair of resistance. When doing a chamber verification, they will drop right in.

Or you can use the CH Tool and Die "Can tool" to put a cannelure where ever you want.....

Then use a Lee factory crimp die to finish it off right.

@Capt_Oscar ..... Why all the fuss about cannelure and crimping to begin with, aren't your .500ne both single shots?

 

[Capt_Oscar]

They are both single shots but the seating die doesn't take out the case mouth flare if you cannot roll crimp into the cannelure. As such the loaded round doesn't fall into the chamber. The case rim is actually a few tenths from going flush in the chamber.
As far as I know, the Lee Factory Crimp die is only a custom order and for many would be cost prohibitive. Taking the guts out of your sizing die is a inexpensive way to achieve the end result...
Never heard of the C&H Can Tool - I'll have to look into it further as there are some bullet manufacturers that don't cannelure any of their bullets.

I had Lee make a Factory Crimp Die made for my 500 Sharps 2 1/2' (50-90 Sharps), At first they said they couldn't do it (don't know why) but I convinced then to give it a try. As I remember the cost was about $40, certainly under $50. Not expensive and worth the hassle.

Lee has made a custom Factory Crimp Die .500 Jeffery for me, using a 1" thread die body. I sent them 3 dummy loads with 570 grain Woodleigh SP. I don't remember the exact costs, but well under $100. Cheap when compared to the cost of brass, 3 die set and bullets. Worked perfectly.

Easier than making a new cannelure ring.
Lee's lead time today is longer.
I got mine in under 4 weeks, pre- Commie Chinese Virus.

In their instructions Lee states that a bullet needs no crimp groove as their Factory Crimp Die will form a crimp groove while crimping if hard pressure is applied.

I wonder how well this has worked for those who have tried it.

That’s the first thing I’d try.
Just take the deprime stem out of the full length die and smooth out the mouth flare.

Yup, works like a champ. I've been doing that for years to taper crimp paper patch for my 45-90 and any bullet without a cannelure such as Hawk bullets.

It does form a sort of cannelure in the bullet, really more like dents in it, holds the bullet tightly. The only downside is that it works the brass more than normal, not a problem on common brass , but rare and expensive brass needs more frequent annealling

Lee's website shows the Large Series Factory Crimp Die available at $125. "Cost prohibitive" is a subjective term, but I doubt that many on this site are on Welfare.

I get it... But why spend $125 on a special die when you already have the sizing die at your bench and all you need to do is remove the decapping stem??
