Leave the long range shooting for the target range which is a fantastic sport in itself .
Sure , there's going to be examples to contrary , but they are just examples and do not pertain to the majority of hunting situations , let alone ethical hunting . The further the distance , the greater the chance of error . The objective is to kill cleanly and as humane as possible . A slightly missplaced shot , no matter what distance , and that critter is going to run . This does happen alot more than some will admit to ....no matter what size of caliber , and then the shooter has to cover the distance he just shot plus the turf the animal has covered . Even a wounded Whitetail can cover alot of ground in seconds .
Military snipers take out targets at 600yd+ using .308 and 30.06 which takes a helluva lot of training , ammo and time to do. If you don't reload , pick a good common , less expensive caliber that will be friendlier to your shoulder as well . Less $$ / pain = more practice = more experience =genuine satisfaction .
