most are ok with a donny on them to shoot in the yard, repetitive shooting and people know pretty much what your doing, and theyre gonna hear it and know what it is when you smoke 'midnight' for hunting your livestock .. in a similar situation where the ultimate one unnoticeable shot near the neighbors from hell fenceline is needed a prod with a sumo on it is the tool for the job ... have the hole pre-dug .. ultimately though if you shoot and shoot 'any' gun it becomes clear whats going on, you cant hide the smack from the report, no matter how faint .. as said though, just about any gun will be fine with a donny as far as noise level, its just a matter of people knowing what youre doing anyway and getting all karen on ya .. dont let them see you .. thats the key ... they cant attack what they cant get to .. if they touch the fence its trespassing at that point, and ud recommend filming it first, then maybe emptying a can of bear spray on them for trespassing and threatening you ...
