The 900 yard club was set up I believe by Dick Idol and David Morris ( I may be wrong on the originiators). It basically takes the score of a hunters 6 best whitetail bucks, adds them together and if your total score breaks 900", you are in the club.
From my understanding, it was thought up to seperate those that occasionally kill big whitetails from those that consistantly kill big whitetails. I heard Dick Idol talking about the club one time and his comments were that anyone can get lucky and kill a Booner but there is no luck involved in killing 6 whitetails that average 150" in B&C score.
Deer have to be free range wild whitetail.
You can run a search under "900 club, whitetail deer" and some information will come up.
Its certainly easier to get into the 900 club out west here or in Canada but its still a difficult thing to do. I have been aggressively trying for this club for the last 10 years. I have heard it generally takes an average of 17 years to get qualified for this club. IF that is true, I have been very fortunate.
I have 8 whitetails that would make the group in different combinations. Here are my largest 6 whitetails to date from oldest to latest:
151" B&C 5x5, Montana
145" B&C 4x4, Montana
152" B&C 5x5, Montana
160" B&C 5x5 Alberta, Canada
161" B&C 4x7, Idaho
144" B&C 4x4, Montana
To be honest, my personal goal has always been 950" in my best 6 bucks. Have a ways to go for that as they all have to average around 158" but someday it will happen. Good start though.
