To state it another way, I use 7X57 dies to load 7X57R.
Normally, the 7X57R is loaded to somewhat less chamber pressures than 7X57. Still, given the generally longer barrels of 7X57Rs, with slow powders and 175 grain bullets, I can easily get nominal 7X57 velocities and have no pressure-related issues. All failures I have had with Norma 7X57R cases have been neck splits, commonly after about 10 firings. I follow my normal practice of resizing cases only enough for them to chamber easily, basically, resulting in cases seating on the shoulder.
