    Ive loaded up 150 or so brand new starline 10mm in nickel and 100 or so in the starline (brand new) regular brass. The Nickel cases are hard as all get out to seat the primers. I was using WLP for the first 100 but i had so many problems with them seating i changed back to my tried and true federal LP primers. The federals are about a third as easy to seat but they are no where near as easy to seat as the standard brass cases. I know the nickel cases are more brittle but i got the for christmas so i couldnt complain. Has anyone else had this problem? I wonder if they will loosen up after the have been fired once?

    I had a similar problem with WLP primers in once fired Federal cases. Solved the hard seating problem by running all the sized cases through my Dillon Super Swage. The WLP primers seated very smoothly and snuggly (meaning not loose) after that. I use almost exclusively Winchester primers in all sizes and have many thousands of each, don't want to change brands after working up many loads in pistol and rifle.
