I have a pair of Ruger 77 Mark II's that will average 1/2" for 3 shot groups with their favorite loads. One is a 243 that it's best five shot group has been 1/2" and the other is a 6mm and the best five shot group for that rifle has been 3/8". That said both rifles will keep five shot groups right around 3/4" to 7/8" with their favorite loads as long as I do my part.
