Which of these lubri-sizers would be the preferred choice, and why? Looking for all the pros and cons from you guys who have used them. I wasn't sure whether or not there is a difference (other than color, of course) between the orange and gray Lyman 450. My tendency is to use more RCBS equipment than any other but I'm not adverse to using Lyman and others if they are superior.
Not looking for more expensive options such as a Star, so please keep the choices to the following:
RCBS LAM
RCBS LAM 2
Lyman 450 (dark Gray)
Lyman 450 (orange)
Lyman 4500
