Hey if you like to shoot targets and the cost of shooting the magnum is costing you more than it should, consider putting in a backyard range. Air guns today are capable of propelling a custom pellet up to 1200, fps now that is pretty dang fast. However they also lose that energy quickly when encountering sufficient resistance, and they are quiet to match. Being a good shot has as much to do with the mechanics of trigger squeeze, breath control, sight picture and shooting position as a good scope or gun.
So by shooting an air gun and practicing the basics you can improve your shooting with your magnum also. What does it take to shoot safely in your backyard or neighborhood, even your basement!
First is safety equipment and gear. Safety glasses at all times in the slim chance of a ricochet.
Space; a low velocity range can be 15 feet, but if you are shooting one of the newer high velocity guns you need 30 feet min.
Third you have to catch the pellet, a box of plywood 24x24x12, lined with a thick piece of carpet, several layers thick. this will catch the fastest of pellets with no chance of it coming back at you if you get it in the box.
Fourth you have to have a backstop behind your box, a heavy canvas, or blanket, with the bottom left loose will help you keep your pellets in your yard.
Now when you set up to hold your targets, get a pair of pipes and drive them in close to the front of your trap. Between these place a piece of wire mesh like 2x3 wire fencing and wire it between the two poles. Use clothes pins to hold your target in place and shoot away, sharpening your skills in a safe manner that is not offensive to anyone. So hone your skills, and increase your accuracy so when the time comes you place your shot where you want it, for a clean and ethical harvest.
