Here are some pics of my pistol target. The Boys took My other two out to a friends farm .
This one is made from 5/8" round rod and a peace of 3/8" plate. Pics tell the rest. This target is shot at from about 15 yards to 100 yards. 38 , 357 , 45acp Have no effect on it. 44 mag with hard cast does. It cups the plate as seen in the pic. This is not a problem I just lay it on the anvil and use a short handled sledge and flatten it out again every so often. I'll say that at 100 yards my 221 and 223 with ballistic tip bullets will make small cratters in it. 223 with FMJ's make little holes , 243 make a bigger hole. I replaced the plate on this one, after I found out what the rifle rounds did. If you have a torch , welder, and time you can make what ever you like. The nice thing about welding the plates to the bushings is. You can cut the welds and replace the plate if needed.
Hope this is what your looking for. Next time I'm out to my buddies farm. I'll get pics of the other two.
They are made the same way but I used 1" rod and 1/2" T-1 plate.
