Don't experiment much with the original setting. Experiment later in fine tuning. To get the seating depth set right, follow the manufacters instructions. You don't wan to set it to crimp for most bolt action and single shot rifles.
Now get a cleaning rod and put a plastic cleaning patch on it, cut off the jag so its flat on top. Run it down the barrel of the rifle till it stops on the face of the bolt. Take a pencil and mark on the cleaning rod right where the rod leaves the barrel. Now pull the bolt out and drop a bullet your going to use into the barrel and hold it into the lands while you again insert the cleaning rod, mark it again the same way, back off just a bit and that is where you start form. Measure between those lines, it's the distance from the bolt face to the bullet tip with the ogive touching the lands. Get the first bullet set to that and one more turn of the seater plug stem and save the dummy cartridge to reset you die with that bullet type again.
