This is the same loader as a Pacific 360. The drawback to the 360 is the primer seating system which is sort of complicated and adds to operating handle effort as you are compressing a spring on the downstroke. If a primer is not seated and powder spills through the primer hole, the powder fouls up the primer seating mechanism and it is difficult to clean out.
In my opinion you would be better off with the Pacific 350 (no primer feed) or the DL 366. The 366 comes in a manual advance version or the 366 auto advance model.
