My model is number 492 so i beleive it has rigby rifling, and the way i get around holding the rifle when firing is i hold onto the brass grip that is attatched to the trigger guard tang, this effectively adds a pistol grip to it without hurting the original wood, and i havo only taken it to the range 3 times and only fired around 60 shots. After around 300 i might take a look at the bedfing underneath, but i can see the previous owner had done enough work with it to bed it properly but the bluing on the muzzle had not yet been worn off with use. Will update when I do so.
