I think I'm gonna start aiming at microrganisms on my 3D deer to get more precise.....

lol

I would honestly like to shoot 3D with some of the people on this site. With quarter sized groups at 40 yds, though.....I couldn't compete. Our 3d indoor course has shots to 43 yds. The 10 ring is about a 3" diameter circle. The 12 ring is about the size of a .50 piece on most. Best round I've ever seen shot is 216.....and my personal best is 208. Some of the groups I see toute on the internet would win every shoot we have.

I've shot with Rob at our course....and he shot a 208 the day we shot the course (to my 204.....and those were our high rounds). 9 times out of 10.....200 would win one of our tournaments.

If I can keep it in the 10 ring from ANY distance......I have no doubts that I can humanely kill deer. My standards increase as the yardages decrease......but I honestly never remember actually aiming for a particular hair or tuft. "I" see a spot that my pin is on (both eyes open)......and I know that's where my arrow is going to impact. I don't understand the "hair/crease/tuft" thing. My arrow's gonna hit where my pin is. That's all I need to know.

Interesting hearing how others think, though.
