I realize that crimped military brass is starting to go away, especially in 30-06 but I still get it whenever I can because if that crimp is intact I KNOW I have once fired brass. That said I have fought with primer pocket swagers for years. My dads old Herters was the best up till now, you still have to pull the case off of the swaging pin but it is nowhere near as violent as the RCBS press swager. And the RCBS desktop swager is completely useless for 30-06. Unless you have a really solid bench and weightlifters arms.
I just got the Lee ram prime, THIS is the one!!! No effort to do the actual swage and the best part is the spring behind the case head that pushes the case off the pin. When the ram comes down the case is already free. Going in is even nice due to a spring loaded cone that centers the case on the way up.
A lot of people bash Lee for having cheap products, well, this was cheap. MUCH cheaper than either of the afore mentioned RCBS units. And it works so much better. Sometimes they do hit one out of the park.
