I full length size my lever cartridges but thats a personal choice. You would do well to make up a dummy cartridge to determine the distance to your lands, back off .005", load a few up with various charges, give them a good crimp and see where you are at on paper. My powder of choice is H4895. With that powder you will most definitely find something between 30 and 32 grains that will put a Hornady 170gr Interlock FP bullet right where you want it.
There are lots of other good options though. Very easy cartridge to load, and a very effective one.
