I thought about crimping...I have a lee crimp, but its for my 30-06. Can I use that same crimping die, or do I need to go buy a 300wsm one? Also, how to you measure the pressure of a "light crimp", do you hang weights, or just feel with your hand? A few years ago when I was loading my 30-06 round I thought I'd try crimping and found the bullets got deformed (i was obviously crimping too much), but exactly how much I never knew. I also use a hornady runout gauge to check for runout, it allows me to make minore adjustments to the runout, which works great as long as its minor...would you then crimp after this step?
For the cleaning I read that "white lightning" oil could be used...would you recommend this?
For the sanding of the mandrel...1500 grit? and how long would you sand, half second or so?...it would be in a drill press
