This can be a tricky one ...... on the one hand ..... ''live and let live'' ..... OTOH ..... ''do unto others''.
I cannot ''see'' in my mind's eye your set up - tho it'd seem you have plenty of space to shoot safely. However, it is also obviously within easy earshot of others.
We have our right to shoot on our own property but .... I think we have to try and effect a compromize to a degree, otherwise we can become ''selfish gun nuts'' and hardly help our side of the fence.
I try and restrict home shooting to .22 - but warn nearest neighbors if bigger cal likely - and that'd be just a few for ammo test etc. I try and look at it rather like - ''how much noise do I want to put up with if having to listen'' ... assuming I do not live by a range per se.
I reckon timing can be a factor - if you shoot a lot and it is random, then maybe because no one knows when - they get rattled that much more. If it was ''certain times only'' .... then maybe they'd accept it better.
It's a hard call and some folks will b*tch regardless. I was up at one local small range last year when a buddy brought his FA Mac10 and we had a blast ... of course! It happened to be a Sunday and dang it - one of the members came up from 1/4 mile awayand moaned ... he tho is one of the members who sorta shoots rifle once a year!
He thought it sounded like WWIII
You'll never please some that's for sure but I reiterate the fact that I think we need to be mindful of others with noise pollution ... which is what it is in effect ... and for non gunnies it grates unfortunately.
No answer will be quite provide the easy solution. Just my 2c... and note ... I am getting old so maybe see things different!!
