Solution for ugly convoluted crimps on Dillon 900SL

Been reading the threads to find a practical solution for this issue with AA hulls, but same with others, 1 or 2 out of 25 is fine, but we are running 10 out of 25, the rest of the shells look perfect. Our old Grabber makes such beautiful crimps, but slow.

Took apart pre-crimp on the 900SL, it is all rotating well. Adjusted pre crimp up down, the crimp die up and down, the only thing left if the powder die, but it looks like the drop tube is the same size inside. We thought the drop tube maybe ironing out the old creases too much, and it may still be the problem here, but is there a remedy?

I know many have sold and bought machines, and will recommend other brands, this not possible now with full ATA and 4H schedules, however we would really like a solution if someone has found one. Thank you.

I get those with shells that have cracks or are just reloaded one too many times .

it looks like your finished crimps on your good loads are a little dished . Mine were like that on my mec. I went to zero wad pressure, IE about as much pressure as I would need to gently seat the wad with my finger tip .

In general , those mutant crimps look like they are shells that were not right before reloading .

Good advice thank you, I will adjust the wad pressure, and have been fine tuning the crimping die as well while measuring all with a Mic. . Older shells for sure raise the odds of the mutant crimps appearing, One of the oddballs in the pics is once fired a few weeks ago, the other "extra light" was shot last sunday by my 11 year old during his doubles match.

Make sure your shot bar is going all the way back. I think you are getting some light shot charges on the dished crimps.
I had that problem and it took a bit to figure out. Empty out all the shot and check the bar travel.

The really bad crimps are the hulls, not the loader. Pitch them the next time you shoot them.

I load those same hulls on a 366 and I have never seen a finished shell that looked like that. I'm going to go with something wrong with the crimp-start. Send those pix to Dillon and see if they have any thoughts.

I very rarely ever saw that when I loaded tens of thousands of Gun Club hulls. Now I load only STS an N27's and I see it occasionally (1 or 2 per hundred) with my MEC 9000. I fault the hulls. I sort those funky finished shells into a practice box marked for immediate disposable. My cull rate is probably higher than most people's anyway...I don't load gold Remingtons more than 3 times before tossing them. When a poorly crimped shell is fired, it's still obvious that the folds aren't right and it's destined to do it again. They shoot just fine but never make it back to the bench.

Agree here, yes, all those go to practice, and may end up getting tested on the old Grabber to see if that repeats. Are the AAs more prone to this? it seems like more people are gravitating to STS hulls from AA. At one time AAs were favored.

Junk Shells....and a Junk Reloader...get a 366 and don't look back
Far from it. I love mine. I notice he is missing the case collator/feeder. I can’t crank out half again as many rounds on my Dillon as the 9000 I run also. I only have to insert a wad, and pull the handle. I load all my 6 pt crimps on the MEC, the Dillon sucks at those, I’ll admit that. No bushings to change, holds a whole bag or more of shot.
