When I started loading the 45 acp several days back,I had some other brass,not WCC,it worked just like its supposed to,and I'm trying to use the same Bullets in the WCC cases and the case will not grip the Bullet,I've tried many different cases and none will work!
Thanks for trying to help!

Just to clarify, when you go to seat the bullet, is it just dropping down into the case? Or is the taper crimp not keeping it in place once it is seated? I have many many many die sets that I have had to take .001" or .002" off the expander ball by polishing. This makes for easier sizing and gives just a little more tension when seating the bullet. What a lot of people don't realize is that the expander ball is used to open up the case mouth. How many fired rounds need to have the case mouth opened? I have had to open up case mouths for wildcat rounds that are a caliber or two larger, or for new brass that is dented from shipping. Most brass is already opened up and needs to be sized down to reload. Sometimes even semi-auto firearms will dent the casemouth during ejection. If you have a universal decapping die (about $10), try decapping your brass in the universal die and sizing it in the size die without the decapping pin in place. If you have already sized your brass, take out the decapping pin and run the brass thru the sizing die again and see if the problem resolves. If it does, your expander ball is too large for your brass. Polish it by placing it in a drill and running with a piece of wet 360 or 600 grit emery cloth to polish.
I have a couple of wildcat rounds 30-20 and 32H&R mag made on .308 bores. If I don't use a .308 expander ball the .312 or .314 expander ball opens them up too much. For these I have to either have powder depth regulated to keep the bullet in proper position for crimp, or I have to resize without decapping stem.
Good luck, I hope some of this helps.
