Hunterbob I though missing/ bad shot placement was my problem ty first shot was 257 yards and I went out and there was blood and hair and I said maybe it was just a bad shot so I decided I was going to take the 308 to one of my shotgun holes and shot the second one at no more then 10 yards so I no they weren't misses, but for the one who asked what I consider long range I'm comfortable with my 22-250 to around 250 everything after that I try and use the 308 but I'm comfortable on a woodchuck a 400 450 on a calm day lol may not be the furthest shots but seems far to me
