Use RCBS dies myself and am happy with them. I do pretty close to what BobinHH does. When I first set up the die I bottomed out the die then started backing it off a little at a time until the cases started being a little hard to close the bolt on, then turned it in a half turn and tightened. For hunting I use once fired cases that have been fired in my rifle. Don't want to run the chance of having a jam when hunting. Anything that has been shot more is used for practice only.
