when u said light loads my thinking was my cowboy action loads. Ya'lls def. of light is a bit different than mine.
200 grain cast bullet over about 6 grains Trail Boss...sadly gone for now.....you can go to 5.5 but it sux, 6 grains ignites better,and I like that I can see them large grains in that large case while setting the bullet in place.

..most of u won't like this load it smokes the cases but...it's light !!
