Guys, thx for all the help, my problem is I have over 1000 cases, what I did was my Dad and myself went and bought a RCBS power case motor that fits our RCBS case trimmer and after some trial and error (my error mostly) the thing works great! I cannot believe how accurate and easy it is to use, I did have to go out and replace a clamp but other than that it is nuts on, I trim 10 cases and measure the last one and if it is on,and it is always on with this machine I go to the next 10. It works fine on nickle plated cases as well, can't say enough of good things about RCBS. I cannot say how many man hours of work that this thing will save but I know it will be alot
