JTKNIVES, You will want to use faster powders to achieve your goal if you are set on using the 10mm in a (Lite) configuration...the reason is the slower powders need to be loaded fairly full volume to get it to burn properly. Bullseye or Power Pistol might provide the results you are looking for with out being position sensitive with lighter charge weights.
If you go too light you will want lighter recoil springs as someone suggested, to have reliable function. I use the Wolff non captured rod and springs with an assortment of spring weights.
I have a 40S&W conversion barrel which allows me to play with various loadings and also saves wear & tear on my 10mm brass.
