Seems a lot of posters to this thread think a 6-pointer ain't a mature deer, period. In my part of the country, a 6-pointer is a mature buck a good many times you see one. Around here, a spike or forkhorn can be a mature buck, but that's a problem with feed/forage and genetics.
Also, most posters here think a buck will taste gamey. My 3-4 year old 3-point buck last fall was a surprise... didn't taste gamey at all. Now, to those who disagree with my shooting that one, there's a couple of reasons why he needed taking out. One reason was his genetics didn't fit him to pass on the genes for big antlers to another generation of bucks. Another reason was that broadhead with 10-12" of aluminum shaft he was carrying from when another hunter pulled the shot and put it under his spine and over his guts. And he was still out there running the does with that arrow in him. Despite all that, the steaks taste real good, especially grilled over a mesquite charcoal fire.
