Well, today I had a real nice bird come in. He was in full strut the whole time coming in for 100 yards. It was really an awesome experience for only being my second time turkey hunting. I passed on that bird because he only came into 40 yards and there was a little too much brush between me and him most of the time. But there was a moment for about 25 seconds when he came out of strut and peeked around the bush a little that I think I probably had a clear shot. I think he just got spooked by the fact that I wasn't using a decoy and he didn't see a hen, so he just turned around and walked off. My question is how do you guys determine your range... because now I think about it, I think I could have shot him in those 25 seconds right after he came out of strut. When I patterned my gun, with the load and chock I'm using I could get between 15 and 20 bb's in the neck and head (mostly in the neck) at 40 yards (on a lifesize target). Is that enough to kill a bird at that range (I'm also using a 20 ga.)? I guess I'm second guessing my decision even though if I was in doubt I know it was the right one... but am I being a little too conservative?
