At MoJam I picked up my #1 and #2 hunting tips made by Scott Stanberry from Jacksonville, Illinois. [email protected]. The one on the left is dark brown obsidian from Oregon I believe and the one on the right is flint from the upper midwest (Mississippi valley). Each weigh in at 146 grains. I will hasp them on bamboo shafts with Missouri wild turkey wing feathers donated my numerous MWT members. Finished arrows should be around 560 grains there abouts.
