My son and I have killed 5 BT with a 20ga slug gun. No added meat damage over a rifle. Good shot placement into the lungs or heart and you won't waste meat.We used a solid copper slug and every shot was thru n thru. Even had one hit a bit back and it vaporized the liver. Buck was dead on his hooves. Your plan sounds good. You didn't mention if you will be using open sights or a scope. If using a scope you are easily good out to 100yds. I am comfortable to 120yds with my slug gun. Although wind will have more effect on slugs.As others said, get a trail cam out and build your blind in advance.Good luck and most of all have fun
