I put empty 38 Spl, 357 Mag, or a custom sized and cut down 30-30 brass into the pan of my powder scale and dribble small birdshot until the weight is about 150 Grains.
A quick pass through a propane torch flame and I have a throw away blunt.
Keenan, has taken this much farther, and I'm eager to try to duplicate (In a fashion) his wicked looking arrow heads.... Tough to call something that menacing a blunt...
Having an arrow that grabbs the turf and acuses the arrow to tumble on top of the brush like a $3 + Zikey Judo rather than burrow in, never to be found, like my current arrows, is also very appealing.
I also, am going to explore the Nutter concept. I have several 3lb coffee cans full of saved hardware. There should be several old 3/8" nuts in there. Being a world class cheapskate, I love the idea of free Blunts.
I appreciate all the feedback.
