I was passed down a '55 300 H&H. It had very little use. In it's original stock and shooting '50's silvertips that came with the rifle just over 1". It is in a beater stock now that I bedded. With handloads it will keep a good load at 1/2" at 100 if I do my job. Unless the rifle is really beat I would expect as good or better accuracy than rifles available today.
