That's about as heavy a crimp as you would ever need.
What caliber is it? You only need to crimp if you have a special need like a heavy charge of spherical powder or loading for a gun with tubular magazine.

It's plenty heavy, it looks as if you've bottlenecked the case a 16th or so. If I go any further than a simple rolling in on the bullet I back off the crimp.
It's for 38 special. The load is 158 grain lswc. The charge is 3 grains of bullseye. I just recently purchased RCBS dies. So I was hoping I did this right. I'm used to loading with a loader.
Will this crimp make pressures soar with this load???
The bullet is a remington 158 grain lswc by the way.
it won't jump the pressures up.
it might scrape at the boolit though.
I don't even crimp many of my target loads and some I just taper crimp [yes they make a 38 special taper crimp]
but a light-firm roll crimp hurts nothing.
You can crimp any round you want, some people crimp everything and some others, like me, only crimp when needed.
Examples of crimp needed:
1- rounds for a tubular magazines so recoil doesn't push bullets in.
2- Rounds for a heavy recoiling revolver so recoil doesn' pull bullets out.
3- loads using certain spherical powders that need the extra pressure to burn more efficiently.
In your case, your load doesn't need crimping at all.

For 38 special my guideline is remove the case flare applied to allow the bullet to fit into the case without scraping. Plus just a tiny amount more so I have a barely noticeable turning in at the top. 45 colt same thing. 357 magnum also.
With a roll crimp if the case isn't the same length it won't crimp the same amount. Most don't bother to trim length of straight walled brass. For range pickup brass I do trim so they all are the same length, and then I keep them together so the stretch will be same across all of the brass. For new I try to keep brass together.
Scrap.... because all the really pithy and emphatic four letter words were taken and we had to describe this source of casting material somehow so we added an "S" to what non casters and wives call what we collect.

I crimp my 38spl, well at least I say I crimp my 38 spl.
I 'am' using a crimp die, but really I am just removing the "flare" from the case mouth and (ever so slightly) rolling the case mouth into the crimp groove, But I'm not crimping the case into the boolit where lead alloy is being displaced.

Thanks for all the help guys. But with this crimp that I'm doing will it increase pressures enough to damage the gun I'm shooting them out of? The gun is a smith and wesson model 67.
Like I said. It's only 3 grains of bullseye. And a 158 grain lswc. Oh and a winchester small pistol primer. I don't want to blow this gun up. I like it very much. And by the way. Leading is not an issue at all. This gun shoots them very well.
If you say I don't need to crimp at all. Can I back the seater die which is the crimp die back up. Set the lock ring and just seat the bullet??? It's rcbs set 18212.
That's what's strange too. After I remove a case I can get lead and brass slivers off the case if I use a toothpick to scrape it.

probably the case.
when seating and crimping at the same time a little sliver of lead and sometimes a shave of brass is common.
if your gonna crimp do it as a separate step.
but your seeing the reason why most of us don't crimp.
adding the crimp will not increase your pressures enough to even notice with the load you are using.
From the die itself after I complete the loaded round Sir.
Should I get a factory crimp die? And just use the 3rd rcbs die for seating the bullet?
