When I first started loading .223 I had the same trouble and found that the problem was I had the seating die screwed to far in to the press and it was causing the top of the case to bulge right where the taper started.
You could actually see a very slight bulge when holding it up to the light: I then confirmed it with a micrometer. It's easy to determine if this is the problem, just mic the empty case and then check it again after you seat the bullet.
If you find this to be the problem; bring your shell holder up to the top, screw the die down until it stops and then back it off about two turns. That solved the problem for me.
