miscou kid, two things I have done to my .22 CMT2 target rifle built on a Mark I Cavalry .450 calibre carbine to improve the trigger pull. First, you can thin the trigger spring down a considerable amount and this will lessen the trigger pull. Secondly, take a look at the sear and the top of the trigger to make certain the contact surfaces are square to each other. If not, stone carefully to correct engagement.

Good luck and don't get in a hurry!
