What did I do wrong with this crimp???

Nothing!

(Shrugging)
It looks like a "profile crimp" (intended for a square cannelure on a jacketed bullet) instead of a roll type crimp.....??

[marlin39a]

Looks like a Lee FCD did that. I use a roll crimp on revolver loads.

[JonB_in_Glencoe]

FCD...looks good to me

If it chambers nothings wrong.

Looks like a good crimp to me. I like that type of crimp.

I say go with it I have some that done that use of the FCD and it is no problem and chamber with any problems.I say go with it .That looks like the LEE 310gr boolit.

Ok, I give up. What DID you do wrong with that crimp?

Dang nice picture.

Were you going for a std roll crimp ?
If your round drops in & out of the chamber, there is no problem. If you want a roll crimp, then you have some careful die adjustment to work on.
The only way to get a good roll crimp is to start with cases of equal length. That means case trimming, really only necessary for HOT LOADS in cartridges like the 3 original Mags. And the later .454, .475, .480's.
The S&W .500 & .460.

If you don't care about a proper roll crimp then use a taper crimp or the Lee FCD.

Usually that first trimming is enough for non-magnum loadings. It does help when using match .38spl brass for top notch target loads.

And trimming did matter to my accuracy when I shot .44Mag in Production Revolver in Handgun Metallic Silhouette 40yrs ago.

But the only thing you need from a revolver crimp is to hold the bullet in the case 1st round to last round.

Looks to me like a heavy attempt at a roll crimp. The "crimp" diameter is rounded off and the smaller diameter of the die's ID, beyond the crimp is apparent in the smaller diameter.. I would back off until the "straight" part is gone and the roll is complete in the groove. Look at the inside of a crimp die. The sides are straight up to the rounded "shelf" and then a smaller ID. It looks like you are pushing the case up beyond the rounded "shelf". Probably won't hurt anything as is, just looks funny.

I use a standard roll crimp, a Profile crimp and a Lee collet crimp on my 44 Magnums. I use mostly lead bullets and if I'm using a heavy charge slow powder (WS820) I'll often use a heavy Profile crimp. Most other loads I'll use the Lee collet crimp.

A roll crimp like in this thread:

Again I mean no hurt, harm, anguish or turmoil by my post I have posted on this posted subject. I am not baiting, trolling or calling out anyone. I am making a post based on my experience, knowledge and/or belief or opinion. That is all.

I got an unfired box of 150 grain lrn from Winchester in 38special where the "good crimps" are like that photo of yours. Personally I don't think its good or bad until you fire it, and see what the gun tells you.

If it chambers nothings wrong.

EXCACTLY what I was thinking, also.
