I have asked this question on other forums, contacted police (both county and state), contacted state representatives and lawyers and none seem to have good answers or want to touch the subject. I know of the federal law Title 18 Part 1 Chapter 44 Section 926a that only refers to carrying a gun across state lines in four wheel vehicles. My question is about long guns(shotgun or rifle) being carried to a firing range or trap club. The trap clubs I would go to are fifty miles or more away and would require going through three county jurisdictions as well as Maryland state and various town police areas. I did make one trip last year with the gun in a soft case slung over my shoulder and no ammo last year. No problems but one deputy in my county did follow me for a few miles like he was trying to figure out what to do until I crossed into another county. After seeing several LEOs post in other topics on this forum maybe a consensus can be reached for what and how to stay out of trouble, I live in Maryland, a decidedly unfriendly gun state.
