My arrows have the brass inserts and I figured I would need some down the road and rather than buy 1 dozen a time I played around and made some.Not perfect and carbon copies of one another but they are spot on for weight and they spin test great.I have used 4 of them and am pleased so far.They cost about $1.50 a piece to buy with shipping and 4' of brass stock cost me about $25.With my free time and my dad has alot of that on his hands I think it's worth while.What the group think?
