I was wondering what everyone shoots? I got tired of paper at a young age and have since spent a fair amount of time picking various thinks to put holes in.
For my .22 cal weapons I favor the spining metal target stands, Dr. Thunder soda cans ($3 for 48 at your local walmart), a 5 pound bag of flour and a 6'x8' piece of corrugated metal I picked up at the dump.
The spinning metal stands are self explanetory. The soda cans explode when you hit them and they are a resonably small target. Great for setting up 100 yard shots with a .22lr or practicing cqb stile carbine drills on multiple attackers. The flour is just plain fun since it makes a mess but you dont have to clean it up. And the bigass corrugated metal is great for long distance shots. We tape target to the metal and then if you miss due to improper windage or elevation, you know where you shot and can correct for it. This in itself has made me a better long distance shooter.
For my .30 cal weapons we use a 5 gallon bucket filled with cement. The bucket will jump when hit and usually sends a blast of cement into the air. Once the middle is erroded out we tape up the holes and fill it with flour for the same effect as the bag of flour mentioned before. Cinderblocks are also fun to destroy, but you dont get much milage out of them. I have 4 6" pieces of pig iron that are 1" thick. I hang them from a kids swingset sized frame work by 2 pieces of clothes line. The clothes line goes to the support in a V shape. Theyre all at different heights and I put the stand at about a 22* angle from the shooters so after you hit one of them the target begins swinging side to side and is harder to follow up.
For my .50 we shoot propane tanks, cinderblocks, tires, cracked 4cyl blocks and just about anything else we want to see explode.
Tannerite is fun but too damn expensive.
What's everyone else use?
