i dont really want to really get anybody exited but i really dont think you should shot any deer past 30 yards. i know there is some relly great shots out there but that deer can do alot of things before that arrow gets there. it also a whole lot different shotting a nice buck then shooting at a 3d target. i know because i missed a nice py buck 3 years ago at 20 yards and if it was a 3d target in my back yard i would kill that deer proably 99% of the time!!!! i also see in alot of these hunting video these guys are shooting at these deer at long distance and are missing most of the time. now far as moose and other big game i have really never hunted them before so i dont know.they do seem to have a bigger vital area and dont seem to have as quik reflects, but i dont know. i do know no matter what your hunting getting him around 15 to 20 yards your chance of harvesting that animaland not wounding that animal are alot better. but thats my 2 cents for what ever its worth!!!!!!!!!!!
