HBWC's @ 100 yards

What a great issue no. 271 was.  Bill Duncan's article was right up my alley.  Since I don't compete now I have found fulfillment in taking one firearm at a time from the vault and finding "The Load" for it and proceeding to another.  The article brought back memories from my earlier years on the Nashville PD when we shot model 10 and later mod 64 38 spl. revolvers.  When the sun was behind us on the 50 yd. line I could catch a glint of the Zero reload's silver base and detect its partial parabola...not when I was shooting, but from another officers shots.  I can only imagine the steepness of a HBWC's parabola.  I'm surprised it cut a clean hole rather than tearing the target.  What is the 100 yard velocity?  (It also reminded me of my 1000 yd. competition days when sorting, chronographing, and ladder testing were required to compete at the highest level.)  I would be interested to see that graphically displayed.  I was wondering Bill if you weight sorted and measured the bullets and cases in an effort towards more uniformity.  And then if you had considered firing all rounds through the same cylinder?  Thank-you for your contribution, Brooks Harris
