I built one very similar to the one pictured. Mine was made of wood. Regardless, it’s a great training aid & it it’ll humble a man quickly. I’d add a few pipes to one side to simulate a ranch gate. Otherwise, it looks good.
This past Friday I had a really good day shooting off the barricade out to 475. I went back Sunday & I did well until I didn’t. Everything went to shit all at once& I almost couldn’t buy a hit. I was really frustrated. I proned out, took my time & still couldn’t get hits on what should’ve been “gimmes” from those ranges.
My buddy shot a few rounds from my gun (all misses) & he downloaded / made safe & started trouble-shooting only to realize my rings had come loose. I felt much better afterwards knowing it was an equipment failure vs poor shooting.
