The Very absent OP also pointed out that the Deputy came, found nothing wrong, and left.  This is how most of these calls go.  Yet, I pointed out three actual calls where someone was shooting with no backstop at all.  In those cases, we came we found something wrong, and took a report. Charges could have ranged from Disorderly conduct to reckless endangerment.  In addition civil action could have been filed by the victims.  Note that the range law does shield the range owner from civil and criminal liability if they are following the " suggestions " and they are shooting in a safe manner and within the prescribed hours.

I don't think it requires an engineering degree to determine if there is a backstop or not and if rounds are leaving the property or not.  Likewise, if the loud booms are rattling windows off the property, I don't think I'm required to measure the exact decibel level to determine if it's loud.

Personally, I think the calls are bothersome, but I don't get to choose which calls I answer or not.  If someone wants to dispute my determinations when answering such a call, they are welcome to bring their experts to court.

As to question 1. Disorderly conduct does not have a Db limit per se. ORC 2917.11A2.  Let them argue it in court with the complainant. I've actually never cited one because most people are considerate if they are advised there might be some issue no different than some loud stereo complaint. Note that the range law does in fact provide relief from this section and civil liability,  if one is following the recommendations.

You of course are well aware of this but simply want to push the argument for it's own sake and your personal entertainment.

As to #2, It depends. If bullets are not going off property, no problem.  We have one guy who shoots into a hillside, one who uses a ravine on the property.  No danger, no harm, no foul.  This is Ohio where properties are somewhat smaller than one might encounter out west. Most properties where people shoot are between 3 and 100 acres.  Trees unless very thick forrest are probably not a reliable backstop.  This is why one of our members took a round through his front door from a neighbor roughly 1 mile east and took rounds in his back yard from another neighbor about half a mile south.

Most of the time, unless there really is some real problem, I take some minor enjoyment in telling new city bred transplants that this is the country and shooting is legal here.  As noted over many years there are very few real problems.  I kinda feel sorry for our fellow arfcommer having taken incoming at his house from two different directions.  He has a 200 yard range with a safe high and wide backstop that I'm sure he would have let those fellows use if they had just shown up and asked.

We are now at 8 pages because some guy is worried that the cops were called, found no problems, and left. He was cooperative with the officer who was just doing his job, did not violate his rights and can now put the call to rest.  Next call, the neighbors will be advised that there was no problem and that will be that.

Not if i see the shooting range and it seems safe and inside the stated hours.

Again you want to argue based upon your personal belief that some grievous wrong is being done to the alleged range owner, when in fact in the real world, most would see the most straightforward way to avoid problems.

Given that I'm the only poster who has offered real advice to the OP, which boiled down simply would be, follow the law, and don't be a jerk, What exactly would your advice to the OP be in his stated situation???

Actually, I stated it does meet the definition of the statute, unless.

In addition, machineguns are prima facia illegal in Ohio unless it is a registered NFA item.  Tannerite is also illegal in Ohio ( OP probably didn't know that as it's a recent statutory change ).

My key point was that there is more than enough to mess with OP over should the cop be inclined to do so.  As an alternative, the OP can do exactly what he did, and all potential problems are avoided.  Plenty of people in this thread offered OP advice that could land him in hot water, but I'm not one of them.

What is your advice for the OP?

Isnt it so much better when everyone tries to get along.

You have now managed to completely bore me.

It is not.

You lost me?

If there were some violation found,  and to be clear, in op's case there was not. It would be a noise violation, or having dangerous ordnance.  Perhaps endangerment if rounds went off property. The only firearms violation would be a possible unregistered mg, which again in this case there was not.

Since its a recent law change. I dont want someone to get in trouble because they didnt know.

If the range law is followed was the qualifier . We are back to i came i saw, i left. Many people have their own range here me included. I cant recall once that i had a bad encounter with a landowner, including the two shooting their neighbor's house.

When answering questions here i tend to default to the worst case of what ifs.
