Very reliable, very accurate. I have 4 52D's as well as a 4 40X's. Three of my 52"s have a special scope mount made by Ken Viani, sadly they are no longer being produced. I shoot benchrest matches with mine and do fairly well with them. Mine are not collectors' items, at least not to me. I will agree that parts such as triggers, action screws and such are a little hard to come by, but they are out there. The 52 triggers, as opposed to the aftermarket ones for the 40X's, are heavy pull, but you can use to that. Like any other rifle, it takes good ammo and lots of practice, to get the upmost accuracy out of them. I have had and still have several good target rifles, Anschutz, Kimber, Valmet, BSA Martinis and Remington 40X's. The 52's to me seems more balanced and more forgiving than the others.
