I'm with the first 2 posts.

Tell us what dies are you using, and if you are seating bullets and crimping in the same die.

You can seat and crimp in the same die, but the cases must all be the same length, and the die adjusted perfectly.

Much easier to seat only with your present die, and choose one of these,

1. No crimp

2. Crimp in a separate die, I would suggest a Lee FCD (factory crimp die) the OAL of your cases is not so critical. About $11.

Glad to hear you got your problem fixed.

The Dillon taper crimp die is also a good die for crimping.

You have to tell us what powder is giving you troubles.

Ball powders work best in a unmodified Dillon measure.

Extruded powders can be made to work with some tuning and operating techniques.

Ok, you are using a ball powder, good.

When I set my PM on my 550 I first set it with one case in the press charged over and over, measuring the thrown charge and adjusting the PM to get the "rough set".

Then I run the press with every station in use and keep adjusting and checking.

I pull the charged case from the bullet seating station and weigh the charge. Trickle/adjust the charge as needed, reinsert case and operate press.

Repeat until 5 charges in a row are correct (my standard, feel free to modify to suit yourself).

Ball powder for me measures exact. Maybe one charge in 10 will vary .1 gr.

As I'm loading a batch, I will check the thrown charge every 100 rounds while I'm stopping to fill the primer magazine.

Here are some tuning tips,


Some of my PM's are polished.




I have also smoothed up the sliding parts with 400 grit wet/dry sandpaper.
Just take off the burrs and smooth up, do not remove any metal, think smooth not remove.


A powder wheel makes PM adjustment easy, put away the 7/16 wrench.
A 3 inch diameter, 3/16 thick piece of wood, with a 3/8 hole in the middle filed out to press fit over the 7/16 hex bolt on the measure.

Your pics could be a little smaller.
Good luck

Are you hesitating at the top of the stroke to allow the powder time to enter the case?  Even using H335 it takes a second or two for all the powder to get into the case.  IF this is the cause, then you need to pause when the ram is at the top of the stroke, when loading pistol calibers it isn't needed, but with bottle neck rifle cases, particularly 22 calibers, with their small neck you need to allow a little extra time for all the powder to flow into the case.

In for update.
