Thank you all very much for all the input on my questions I appreciate it.
Now I still haven't had the chance to take a Whitetail, still itching for Deer season, but I did take a trip to visit friends in Oklahoma. Also had the chance to take my Weatherby Vanguard 300WM. with me. We were out on her family's farm taking care of some Feral Pig issues they have been having. I hit one dead in the shoulders, I did that on purpose, at 132 yards. I squeezed the trigger, bang, it dropped where it was standing. Bullet hit exactly where I aimed complete pass through. The damage was sick, I had always read about the shields on the pig shoulders stopping some rifle bullets. Is this indicative of what I can expect on a Whitetail?
Pig was 132 yards and weighed in at 214lbs, not huge but still. I now have a better understanding of this "buck fever" people keep talking about I was nervous at the shot and was shaking a bit but my Uncle had taught me shooting techniques, controlling my breathing, calming myself, and all. Took a few moments to do and I was dead on it. I am going to try this coming season to go for the front shoulders on a fast shot but if I can calm down and stay steady I'll put it behind the shoulder. That was a first for me on the shakes while trying to put the cross-hairs on the animal. That's hard to do.
