Profile Crimp die help

Just bought a new Redding Profile Crimp die 38/357. This die does nothing but a light roll crimp. There is no resistance in the press handle at all until you hit the roll crimp portion of the die. In fact, if you remove the die from the press and invert it, a resized case with a 148 wadcutter fully seated will fall into it until it hits the roll crimp shoulder. Bad die from the maker? Thanks for any help you can give.

Tom, what exactly do you want the die to do that it isn't doing now?

dozen

Doesn't sound right; should be a taper leading up to the roll.

Bad die?

Flare a 357 case then run it through the Redding; what does it look like?

Profile Crimp die problem

It was my understanding these dies put a combination taper and roll crimp on the bullet. This die only does a slight roll crimp. There is no evidence whatsoever of any taper crimp being applied. If I were to take a flared case and run it through the die, there would be a roll crimp applied, but no taper at all. It would look like any other roll crimped case with a light to moderater roll crimp. Thanks again for the help, this one has me stumped.As Weshoot II said there should be a taper leading to the roll crimp and I can find no evidence of this being the case.

more testing

Okasy, now apply a nearly-case-crushing heavy roll crimp on an empty case; what does that look like?

Profile crimp help

Weshoot II - I stuck a R-P brass (not plated) case in the press and adusted it as you asked. It gives the mouth of the case a bottlenecked appearance much like any other bottlenecked case but to a lesser degree. The reduced diameter band at the case mouth is about 1/16" wide. Hope this helps, Tom

Profile Crimp help

Weshoot2 - That's what I suspected. I've been away from reloading for a number of years but now getting back into it and while I'm certainly no expert, I didn't think I was totally out of the ballpark with this issue either. If you put marker or some other kind of marking material on the side of the case, it comes out of the die totally undisturbed, indicating to me that this thing must have been machined wrong. Thanks to all, especially you Weshoot for all the help. I have been lurking on this board for a while now but find an increasing need to seek advice from time to time. Thanks again, Tom

Should be seeing some taper below that 'band'.

Bad die, ay?

Looking at the picture, I agree. Bad die. Send it back.

The profile crimp (which Weshoot2 suggested to me a while back) is a great die and I basically don't load for revolver without it. Works "perfect".

As always "Thanks to Weshoot2!"
