My brothers and I are building a rifle gong range. We need an elevated platform to see all our targets especially since we will be shooting over soybeans or corn. We plan to make it 10 to 12 feet high with 6x6 posts. The idea is to make it as solid as possible. I’m just wondering if anyone has good advice like we should definaelty make it so long and wide, or tricks to make it more stable. We will be shooting prone off of it and will have 2 to 3 people up there at a time. Thanks in advance for the advice.
