Selfbows

I shot broadheads and gamenabbers yesterday and found they are grouping about 6 inches stiff at 30 yards. I need to work on getting my full draw. I broke one nock, thankfully with a game nabber, not a broadhead. I almost lost a broadhead in the sod I use for a target, but I was able to dig it out. Had to fix 2 arrows this morning, though. I braced the hickory a little higher and used a short straightedge to find flat spots and spots bending too much. After some work with bowyer's edge and a number 50 rasp, I exercised the bow another 50 times. Still too stiff on lower limb and too stiff in the tips on top limb.
