If I had to shoot a conical (and I do by choice when using my Whites) I use a 460 gn in my .451, 85 gns of T72f and 498 gn in my .504, 85 gns of T7. 185 yds is my longest shot out of my .504; a pair of 160-165 yds for the .451. The all lead conicals performed well! I would not hesitate on a 200 yd shot with either; I know the ballistics of each and have practiced at that distance as well. So many better choices than the expensive Powerbelt... IMO.
