I killed my very first deer with a bow, many years ago. I practiced just about every day and could make a 50 yard shot with ease. The shot was a 40 yard, heart shot with a Bear Whitetail II, that only had about 215 FPS speed. I hunted a few more years with better bows and killed a few deer.
But I probably never will get another bow! Some of the main reasons are that it is usually unbearably hot during our East Texas bow season. Also, I can't stand having to pass on a 10-15 yard shot, that I could make at 200 yards easy with a rifle! But mostly it's my old eyes! What I could do at 50 yards with a 215 FPS bow 30 years ago, I cannot do now at 35 yards with bows that shoot 225 FPS!
That, and watching/hearing a deer scream after a perfectly good shot, while I get another arrow out of the quiver to finish the job!
