I load for several different rifles. My main one's were belted mag. I would lose a case with base separation in 3 to 4 firing. There is ways to check for it. I went to neck sizing with my belted mag cases. That stopped case separation at the base. I would generally lose my case to primer pocket getting to large in 10 to 14 firing after that. It can be done with FL dies. Neck spliting will be reduce by annealing your cases. Learn to bump your cases with full length dies, back .002" or close to that. I would go to bushing die at the start that way you are not getting two sets of dies in the long run. That way you can increase the tension on the necks as wanted. Most of the bushing dies don't come with bushing. Those are order out separately. You will need measure inside and outside dia and case lengths.
Unknown just what equipment you have presently either, or I missed that. I am not going to say what equipment by name. That's your choice, and pocket.
YOU NOW STARTED DOWN THE RABBIT HOLE!
