That's kind of what I thought too,but just threw that out there to see what people might know.I bought my said cane at MoJam from a fellow from Texas.Some of them do come in at a nicer 550 grain or more but these did'nt.Did'nt check the the wall thickness well enough I guess.I have a coon hunting friend in Missouri just south of Jefferson City that says there are thousands of the shoots there.Don't know how good it is.He is'nt into bow hunting himself.It's about a 3 to 4 hour drive for me to check it out.Do you have some locally around you?That's nice if you do.
