Forster CoAx is popular.... have you measured the runout of your ammo while using your LEE?
Dies matter a whole lot more then the press in making precision ammo. Now if the press ram is moving in some wonky pattern, then change for sure. But if moving true and each step produces the results we need, a fancy press isn't going to change or improve anything.
Now if you are working with very large cases like Chey Tac and BMG, then you are asking about mechanical leverage.
If you are truly interested in making better ammo, spend the money on quality milligram scales and better brass prep/maintenance tools.
