Great topic and one that frustrates me no end, here in Australia the situation is much worse shooting on public land is banned period other than a few states that allow hunting in some small areas but no target shooting allowed. Sounds like some states in the US have similar difficulty to us down here?? Unless you know someone who knows someone or are related to someone with land you are screwed.
In my view this is the single biggest factor in the growth of shooting sports and most certainly ELR type stuff. Doesn't matter how good your 10 thousand dollar rifles are and how good your reloads are if you don't have land to shoot what are you gunna do?? There are a handful of lucky people who have access to the land whilst the masses are stuck at the local 100yard shooting range!!!!
The closest thing to consistent longer range shooting for most would be f class but then comes all the rules and BS around that and shooting ranges. I have done the yards asking land owners for permission to shoot its basically a 100% knock back rate and I cant really blame them to be honest. Who wants someone on their property blasting away with rifles at steel targets, very little gain for a land owner.
There must be a market out there for people who will pay to use someone's property to shoot long range steel. I'm sure this happens in the US with much more freedoms than down here. There would be too much red tape and bs for a landowner here to have shooters paying to shoot targets on there property. From what Ive seen there are small groups who have access to land and of course this is held in very close secret kinda like fishing spots no one wants others taking there fishing spot. This is understandable but it does little to grow and expand shooting sports further.
