My bullets don't seem to be going in the case straight?

Avoid like the double plague, any old die sets that size and expand in one operation. Picture sizing, then flaring the case, then pulling the flared portion back through the sizing portion of the die. In order to have any flare left, it must first be sized to great excess, so that when it comes back through the sizer, it has to spring back to flare.

?????????????????????? Such a die never has existed. Not for straight walled cases anyway. It's entirely impossible to size and flare in one die. They,(RCBS), used to make .357 dies that only sized in die #1, then expanding, flaring, and decapping took place in die #2. They then came out with a spindle that fit in die #1 that decapped.
