I take every precaution when it comes to shooting any of my guns, air or PB. When I shoot my pellet guns at home, I make sure I have a strong backstop to shoot into which is a 12 x 18 x 12 inch box made out of plywood stuffed with cloths and rags which is then backed with several sheets of plywood and a thick metal sheet sandwiched in between just in case a pellet bores a hole. On top of this I made another another 4 ft x 4 ft plywood stuffed with 2x4 and 2x6 wood which also has metal sheet sandwiched together. Behind this 4x4 barrier, I stacked a four foot high rock wall that run 20 feet along the fence which is located at the edge of our property which make up my 75 yard shooting range facing north. I'm not a paper puncher so most of the time I use my range to sight in my gun or to check my zeros or to test out a new pellet. After all of the precautionary steps I take, I still get very nervous when I shot my pellet guns at home. Our nearest neighbor is about a hundred yards from us but they are on the opposite side of my shooting range. I have one neighbor who is just north-east of my shooting range and they are about 110 yards from the house at my 2 o'clock position. They have a huge 8 foot rock wall that runs around there house which is very nice. This neighbor sometimes make me nervous when I shot on my range but its another neighbor that makes me very nervous because they are directly north of my shooting range but they are 170 yards away. I'm not sure if can call them my neighbor because they are actually in a different neighborhood. My 50 yard target also has rock wall I built and I'm less worried I will mess my target at this range. My 20 yard target is actually inside a smaller yard surround by a rock wall and this is where I mostly have been shooting my prod. If I some how missed my target, missed all my barriers, or I got a ricochet and my pellet some how made it to the house located 170 yards, would my prod's remaining 3 foot/pounds, or less if I got a ricochet, of energy break a window? Now I have to thank God this hasn't happened and I hardly shoot out to 75 yards. I got 3 foot/pounds at 170 yards for my prod with shrelok pro.
