Take it easy on FCD - it works
You don't have to use a bullet with a cannelure to use the factory crimp die. As was mentioned previously, the usual issue with roll crimping is too much crimp. Take a factory jacketed bullet and look at it closely under a magnifying glass. There is a slight crimp that rolls the mouth of the case inward into the bullet, making an almost seamless transition from case to bullet. Try to copy that in your crimp. Make dummy rounds before you load with primer & powder to get all or your dies set the way you need. Overall length is important here, so use an accurate caliper to measure. Follow the instructions for the factory crimp die, using the lightest amount of crimp first and inspect under the magnifying glass to see if you have what you want. Make a few dummy rounds with different amounts of crimp to compare. Be sure to seat the bullet to the correct OAL, using your caliper. You can always go with more, but cannot undo too much crimp. If you split the plating, you have gone too far. If I remember the directions, start with about a half turn more of adjustment after firming the die to the seated bullet. Check your crimp and adjust from there. You will be pleased with the results. I load Berrys plated 158 gr flat points and they work very well. Best wishes,
