It loads with moon clips so head space is not an issue. Can I cut a cannelure in the bullet they roll crimp for a smooth reload ? Has anybody tried it yet ? I know I can chamfer the charge holes,

Thanks,Keith

Yes you can.

You can probably even get away with roll crimping slightly into a bullet without a cannulure enoough to break the sharp case mouth edge.

CH makes a cannulure tool if you decide to go that way.

But I'm not sure who, if anyone might make a .40 cal roll-crimp die??

But regardless of all that, you will not get smooth fast moon-clip reloads unless you chamfer & polish the sharp edges of the chambers.

Tool and a profile crimp die but will get what ever I need to make it work,

Thanks,Keith

Also rounder bullet profiles with no shoulders (like a semi-wadcutter) or meplat will help too.

Not exactly the speed reloading your talking about but this device has been the most usefull item for my moon clip revos.

You don't have to go nuts with chamfer. The faster my reloads became the more I noticed that I was more or less throwing the rounds at the cylinder. They seem to glide right in when your fingers are not on them.

You could taper-crimp into a cannelure if you had one.

I can make one I have the equipment Unless Big Brother Outlaws that to while there taking out guns ,

Thanks,Keith

Sure, you can change crimp styles, but I guess I wouldn't expect to gain a lot of speed from that change.

A noticeable change would be in breaking the sharp edges of the chamber mouths, and a much greater change would come from actually chamfering them significantly.

Then, as owen said, use the pointiest, roundest/smoothest profile bullet you can find. No SWCs, at least a truncated cone style, and a round-nose, hardball profile is even better.

If you're talking about speed loading; ie., getting the cartridges into the cylinder, try a taper crimp. Just like feeding a round into a semi-auto chamber, a round with no hard ridge (taper crimped case mouth) will enter the cylinder smoothly.

[Float Pilot]

Taper crimp die or Lee Factory crimp die.
Use a tapered , smooth jacketed bullet.
Round the sharp edge of the chambers just a touch.
Make sure your grips are not making you load at an angle.
Practice with dummy rounds.... A LOT....

In a stroke of genius, I came up with the cheapest and most practical solution:

Use a lighter weight bullet, like a 135-155, seat it deeper so that the ogjive is about .030" deeper than the case mouth, and put a heavy taper crimp over the shoulder. That way you won't need to cannelure the bullets and you'll have the benefit of easier chambering and increased bullet pull.

[kidcoltoutlaw]

Did the pressure go up with deep seated bullets ?

[918v]

Yes, that's why the lighter bullets so you maintain the same case volume. For example, use 180gr load data with deep seated 155ggr bullets.

[kidcoltoutlaw]

Would there be an advantage to using 10mm cases ?

[rcmodel]

Or, you could just chamfer & polish the sharp chamber edges.

They will dig into the cases themselves, and slow speed-loads regardless, if you don't.

Yes. You could use heavier bullets. With .40 cases I would not go over 155grs.
