My folks are building a new home on one of our farms just 6 miles up the road, and i am trading all the concrete work for a shooting range. Dad is going to add another 8' on to the back of the new pole barn, or his hot rod shop as he likes to call it. I will have a room 8'x32' to make my shooting room with. I am only going to have 2 benches, one for me and one for mason, my shooting Pard or my dad or who ever. The benches will be concrete set on blocks and i already have the tops done. I though about adding another bench but i have plans for a lathe within the next year so i will need the extra room for that. My dad is a tool maker for GE so i have a free teacher, plus i though about taking a course at our local junior college. What i am abit unsure of is what to use for the shooting ports. I figured a standard 32" window would work but i am not real sure. The barn is brand new and i have to keep the appearance clean so i cant think of anything else. I am also a bit concerned about muzzle blast. the windows will be up of course but this is all new to me and i have never shot inside a building before. We will build an inside wall to separate the last 8' of building that will be mine and i plan on insulating the heck out of it. There will be 8' ceilings and i will also insulate that. Do you think regular pink insulation is enough or is there something better to use? Just looking for comments and ideas. I think my plan is pretty solid other than window size, but i am open minded to any ideas from you fellas that might already have such a set up. thanks Lee
