Sorry my error on the caliber. I missed that post.
I don't know how familiar you are with the M swage dies (I think Dave is calling them the Pro Swage now) but for a large rifle caliber your going to be at a limit on the alloy hardness, even then you will have to use that loading press at the bottom of the lever stroke to get enough force forming the bullet properly unless you put a cheater on the press handle
I started swaging using the Hemp dies and a Pacific loading press basically the same as a Rock Chucker and I had to make several short strokes on the bottom and screw the die down after every stroke till the bullet was formed. I ended switching to the Herters press.
I still have some dies C&H but they are pistol dies.
I pretty much quit swaging because now days you can get good moulds that will cast a bullet of good quality once you learn how to get a good bullet drop from the mould.
Enjoy your coming trip with the Shiloh. It's a good rifle to start with, just don't get discouraged on that trip.
