I've go a buddy that picked up a new S&W 986 and it favors heavy bullets. I'm looking to try 158gr bullet. Barrel & throats have not been slugged/measured for sizing yet. Figure I have some room to play with the OAL length in the wheelgun since I don't have to deal with a magazine and he is looking for accuracy over velocity. I'd thought of trying to run a wadcutter poking along at 700fps out of it, but that would just look wrong. Powders he has on hand are red dot & 700x.
Any recomendations for a starting point from experience?
