Since I have Been bowhunting biggame 50 years (this year) I think I know where I should put the arrow (anatomy) & I "DO" know how my equipt. works. My decision is based on distance for me-I "know" I can spot out through 50 yards on a target but when I am in the field I keep them under 30 yards 99% of the time. Yes, the position of my quarry, but I am pretty patient & wait for the right shot. Yes, I have passed on some pretty good animals "REAL" close just becausethey did not present the right position.
Win some, loose some. I have let some real trophies pass for several reasons-wrong angle, a little to much brush or just a little to far. Each situation is different but after this many years-I have set my own limits.
The other 1% 2 Elk at 35 yds. a Buffalo at 41 yards & a dandy Buck at 35 yards. Deer, Bears, Hogs, Caribou, Rams & a few others-all under 30 yards. I have been fortunate in blood trails too-pretty short....Good Luck. Common sence is the best guide in the field...I have 34 Biggame animals with recurve & wood arrows &I guess nearly 150 with compound.
