Never been to Friendship. I shoot mostly in New England. I made a rattle trap for our club to use on trail shoots. Used a pressure treated 2X6 about 18" long. Marked out a zig-zag pattern on the board with endings at the centerline of the top and bottom of the board. Used a 5/8" dado bit in my router and routed out the pattern till it was about 5/8" deep. Took a piece of 1/8" plexi-glass and screwed it to the board. The board is suspended from a tree branch at about shoulder height. A empty soup can is hung from the bottom of the board below the exit point of the ball. In use, the shooter drops a ball at the top of the trap and has about 3 seconds to mount the gun, pull back the hammer, acquire the target, (usually a 6" gong at 25 yards) and shoot before the ball drops into the can. Has worked great for us for years, and I still hear groans from shooters when they see this target set up. You have to be pretty familiar with your gun, and it needs to fit you well in order to get on target and fire before that ball drops into the can.
