Duncan,
I was shooting a Fred Bear TakeDown Recurve , 65 lb limbs but I short draw to about 25 1/2" so weight is around 59#, arrows are 2212 Easton Cosmic Eclipse shafts tipped with 100 grn Magnus Classic 2 blade BHs. I fletched the shafts with three 5" parabolic cut goose feathers... Total arrow wt 480-500 grns.
The Magnus 2 blade BHs performed flawlessly. They are strong and cut on contact and cause much internal bleeding. That helped us track and recover the wildebeest as I had hit him just outside the vitals. The Kudu was shot broadside in the center of the heart/Lung area. He ran about 200 yds and collapsed.
