What is "pin bracketing"

I would guess it means stacking the pins, or guessing where you would have a certain pin if you had it i.e. If you wanted to shoot 70 but only had a 50 pin you would imagine where the 60 and 70 pins would be, basically it's like knowing how far to hold your crosshairs over a deer with your rifle.

I sent a PM to Deadi but to all who are wondering here it is in the words of M. Gardner. Great advice...

"We used to get a piece of paper or cardboard and mark out 16 inches for a deer's chest. You will find that when you stand at say 40 yards, that the space between your 40 and 50 yard pins brackets the 16 inches. Do this for 20, 30, 40 yards and find what pins bracket the 16 inches. At 20 my 20 through 40 yard pins bracket the 16 inches, at 30, 20 through halfway to 40 fills the space, and 40 my 40 to 50 do it. Last year I was going to shoot a good buck at 25 and he ran off and stopped. A quick look at what pins fit him and I knew he was at 40 and killed him. I wouldn't have had time to rangefind him. You will need to see how YOUR pins bracket the 16 inch space to determine how to do it. It may be different because the spaces between your pins is different I'm sure. An elk is about 26 inches, so if you are hunting elk determine how to bracket them. This works quite well if you practice it especially on a 3-D range."

So simple yet so good, it makes perfect sense! That is the best idea I've heard in a long time. Now I dont need to shell out the $150 for the rangefinder!

Great info, thanks Mark!

thanks guys I think this makes great sense i am deffinatly going home to check this
