Personal choice, or is that the effective range?
My dad hunted all the time when I was younger. He went through a stretch during deer season where he was getting a deer first day every year for like 9 or 10 years in a row, so he asked for a muzzle loader kit for Christmas. I asked him why, and he said it would give him a project to keep busy during the year, and it would be a challenge when hunting season came, and he felt like he was starting to lose interest because of how easily he was getting his deer. So, he got the kit and built it. The first day of hunting season that year, I felt something shaking my leg. I woke up, rolled over, and it was my dad. He said, "Can you come help me?" I looked at the clock - it was like 8:30 AM. I looked at him and said, "You're kidding." He just shook his head sadly and said, "First shot." I never saw him look so disappointed after a successful hunt than that day. He later told someone, "I thought I'd get a couple days out of it, at least, and I didn't even get a couple hours or a couple shots."
