I'll stick to the original part the tool was designed for. It's worked fine for +20 years with frequent use with the original o-rings. I don't care for the way the press S/H holds the case so loose and rattles. I rely on the rattle to confirm the bullet is out. The screw off nut has a radius where it contacts the radiused factory holder and I don't think the plastic nut will last long using the sharper edged press S/H's. FWIW I pre-load for competition so it gets used several hundred times a year.
One last thing, there were incidents that proud primers were the cause of accidents with these tools, and there is a small margin for error with the press S/H's as they hold the case so loosely that the edge of the primer gets awfully close to the edge of the thru hole of the press S/H. Sometimes faster in reloading is not the safest.
