Put these together last weekend, used some rebar, and square pipe as the stands, a 1/4" thick 20" wide mild steel plate (from some type of stand) my grandpa had laying around for shooting at 1580 yards and four 1/8" thick by 14" wide cultivator disc's my grandpa also had laying around that my Dad welded together that we plan on hanging at 700 yards. We used some belt to hang them from. I am hoping to try them out this weekend, supposed to be very little wind (7-9) mph and will shoot them with a 30/375 S.I. pushing the 215 berger at roughly 2980 fps, and a 284 win pushing the 162 amax at 2890 fps. The square plate i am using as a handgun plate.
