You can make a blunt with an empty .30-cal carbine casing.
I like judo points. They fly well and those springs really tear things up when you hit one and they slam on the brakes when the arrow hits the ground. Be sure to have extra nocks and a drywall screw when you go out. The arrow will flip and sometimes it will slap the ground with enough force to break off the nock. I just screw a drywall screw into the broken nock inside the shaft and pull it out.
Screwing an old broadhead on a flu-flu works really well also out to about 40 yds. After that they drop like a rock. I shoot 60#. At 20 yds I use my 20 pin, 30 is a 35, 40 is a 50. I plotted the trajectory on graph paper so I just range it and find where to hold without having to adjust my sights. I shoot a 4-5/8 long full feather. This is the longest I can fletch and still nock the arrow with my QAD rest with my brace height. I use a three fletch with a 3 degree right hand helical. A left hand would unscrew the broadhead. I shoot with the off feather out, like a traditional bow. I have no problem shooting turkey feathers through my rest although I do get some contact. (lol) After about 6 shots they "break in" and fly like darts. Those big ol feathers really stabilize the arrow in a hurry. If you are getting more contact in one area then another and one feather starts to wear more then the other two, just rotate them occasionally so they wear evenly. I can usually get 50+ shots out of them. They do sound like a rocket taking off though when you let em' fly.
I prefer gateway feathers the best. They are very uniform and have a thin, fine quill. Trueflight also has quality feathers. I have also used feathers from a craft store, like Michaels. They have some nice white turkey with black tips. I have also used the variety pack with the dyed colors. The gals working there always give me a funny look when I am sorting through all the bags to see which one has the most right hand feathers. I split them with a drywall knife as uniform as I can get them, then clamp them in a big stationary clip and sand them with 250 grit. Then glue them on with my bitz.
Shootn' squirrels is a blast and will really test your skill. The first time I killed one at 60 yds you would have thought I just killed a buck!
Check your regs to make sure you can legally hunt with blunts, sgh's, or judo's. I know some states require broadheads for all types of game.
Have fun and good luck!
