Not at all, if the client needs handholding, I want a rifle I can lean over and dial for them if they can’t figure it out on their own. I don’t want to be telling them to hold a “hair high” or “right on the back line” or whatever. I’d rather be able to tell them “dial up 3.5”. Or just do it for them if they go blank.
I would basically want a near clone of my own rifle so that they didn’t feel like I was treating them differently.
A boringly reliable Tikka, Sauer 100, Mauser, etc. in the 9# range with a suppressor in something between .243 and .270 Winchester would be my choice. Throw on an SWFA 6x or 3-9x and call it a day.
I like the suggestion to put a custom barrel marking on it. The “.243-308 Winchester Short Magnum” loaded with Extremely Lethal Deadly Murders, Extremely Lethal Deadly Xterminators, or Terminal Master Killers would be my choice.
