Dean, sounds like your press needs a slight adjustment.

Was unhappy with some of my crimps recently after switching to a different hull. Dug out the MEC hand book, an allen wrench and a twiddle here and a twiddle there, crimps look like factory now.:)
If you have a hole in center, you need more starter crimping.

Thanks Bob - I was thinking I needed a different wad. I'm a beginner at reloading so I can use all the help I can get.

Dean, a great resource for reloading is Gamaliel's reloading forum. Any problem you come up with is in the search feature. As this forum has many very willing to share knowledge it has very detailed instructions and photos on how to correct problems to include repair of the machines. You will also see some familiar people from the Parker forum.

Thanks Daniel - I'll visit that site in the near future.

Dean: A little more starter AND finish crimping(final station) - both simple adjustments - on an MEC press is what I've found to cure this.

Thanks Richard. I'll definitely make those adjustments. I have a couple of MECs (16 & 20) and a couple of PW presses in 28 & .410.

As Richard said, also realize shells are not uniform in length. Remington gun club can vary from batch to batch so i crimp for the shortest and the longest wind up with a swirl crimp. All of them collected over the years, no matter what gauge or manufacture vary and i adjust for the short and put up with the swirl.
