Lovely old rifle. Congrats on a solid acquisition. My local club hosts an outlaw rimfire benchrest match every Thursday night using a variety of targets but mostly the USBR green monster and the ARA unlimited cards and occasional others. We require the repeaters only (no D's or E's) and all must shoot from sandbags only, no mechanical rests. We require mostly factory rifles but light mods are generally accepted like trigger job, bedding, and even replacement bbls. The C and B models of the 52 are the most popular in this match. We average 16+ competitors and fully half of them regularly shoot a Win 52 in this match and they win regularly as well. Other rifles seen are Annie 54/64 repeater models, Sako, Cooper, CZ/Bruno, and occasional others. On the first Thursday of the month we allow any 22 on any rest. This brings out the single shot match rifles and many custom rigs. The old 52's still hold up well in this company. A top grade custom rifle like Turbo, Hall, 2500X built by a competent smith in the hands of an expert marksman can and does outclass all of the elite factory rigs but not every time. The loose nut behind the trigger still impacts the results.
For this match my go to is an old 52B topped with a vintage Unertl 20x. I call it the Ugly Gurl, cause she was used and abused and you can feed her anything and she will still put out. It is amazingly tolerant of most ammo types and lots and has won her share of those matches. On unlimited night, I often deploy a cutom 52D bull-bbl with a Shilen Ratchet and 36x Weaver optic. It has a better trigger and slightly better accuracy (sometimes) or I use a Anschutz 54 Super Match topped with a vintage 20x Redfield. I have a prestine 52B called the Pretty Girl. She is a prima donna and does not come out to play often and has nearly no miles on her. She wants champagne and caviar to put out but will shoot with any of them when fed a diet of Eley Match or Lapua Mida+. She is topped with an old vintage B&L BalVar 6-24x scope.
