Michael,
Don't make the mistake I did. Record books have never been of much importance to me. I hunt because of the hunt, not because I'm actively seeking trophys. But, when I shot my moose in September, after waiting 27 years for the chance, I was heavily "encouraged" to enter it in the Maine book and the Pope & Young book and then, after seeing the current entrys I realized that it really was an exceptional animal, and agreed that it should be reconized. I filled out the forms, waited the 60 days for drying and had it scorred by an official scorer from the Pope and Young Club. It scored high(for all types of bows not just trad bows)in Maine and well up in the Pope and Young records too. By now, I must admit that I was getting a little caught up in this record book stuff. It is fun to compare.
I received the Pope & Young certificate shortly there after, but, unfortunately, while reading an article in the Pope and Young news letter, I discovered that the use of an electronic call would make the entry invalid. It either wasn't on the fair chase affadavit that I had signed or I had missed it. Neither my outfitter and friend nor I had any idea that an electronic call would dissqualify an entry. Heck, we haden't even thought about record books at that point never mind weather an electronic call would be consider not fair chase. My outfitter had agreed to try the electronic call for a friend who was the manufacturer of the call and this hunt was the first time he had ever used one. His mouth calling, we both agreed, was much more realistic, and, in fact, the Bull actually came to his mouth grunt, not the electronic cow call that he had used earlier before he turned off. But, we had used the call during the hunt, so I fealt obligated to withdraw the entry.
You never know when that monster bull is going to show up so, the long and short of this is that you better check to see if an electronic range finder will be accepted under the fair chase rules before you use one. I have also read that even the use of a lighted arrow nock will disqualify an entry.
Best of luck on your hunt.
