I'm not sure if this is the right place to post this, guess I'll find out. I've run into a snag loading some 22-250 ammo using a FB bullet. When I try to gently take the expansion out with the roll crimp in the seating die I think I'm changing the shoulder angle. I think I'm being really careful but they don't do well in the case gauge. I'm thinking about trying a factory crimp die to try and get it right. To add to the problem my rifle is not with me at the moment to see if and how they might chamber. I guess my question is will the FCD be the way to go or am I missing something else. Everything I've loaded with BT bullets have been great shooters. Thanks in advance for any help and again I apologize if I'm not in the right place.
