Innovative Technologies makes a special collet die to correct the problem. But neck sizing removes that little problem and reduces stress on the cases. As long as those cases are shot in the same chamber.
I appreciate the info. That's definitely good to know for future reference since I'll be loading a lot of 7mm Rem Mag and 300 Win Mag. I'll definitely look into neck sizing for my 7mm and 300 bolt guns as well as loom into the Innovative Technology die for my automatic 7mm. Thanks!
