Best thing I ever did with my Hornet was buy some "splat" targets, and load up a variety of bullet weights.
My tests showed the only bullets stable at 100 yards were 50gr. I tried 35, 40 and 45 and they all were tumbling ripping non-circular holes in the targets at 100 yards.
In fact, I was so new to centerfire, I thought the non-circular holes were normal bullet and target behavior, till I shot the 50s...perfectly round holes with a really thin "splat" outline.
