I do a lot of reduction of necks. I have change 300 WM to 308 NM, 300 WM to 338 WM, 280AI to 6mm/280AI's. Some take me four steps to get it done. That's why I lend to to using additional bushing dies so I don't have to change out bushing. Depending what type of press your using. Either rotate the plate or change out the die.
I do a lot more work to my cases that's not mention here.
There been lots of discussion in setting up your cases. I go to the far end of the work on cases to start with. I have change for sure to better grade of rifle cases.
My biggest problem presently I have been without my reloading place to do the work. I am just about to finish my reloading shack. I'll be one happy person when I get it done.
Having to travel around the country hasn't help one bit. Having to depend on others, becasue I am not totally stable on my feet any longer, cause me the problems too. I am a carpenter by trade. so the build wasn't a problem it's my mobility.
I don't like it, but that life.
