Awesome! I shot a Winchester 52D during my first 2 years on the Punahou Rifle Team in Honolulu, Hawaii in the very early 1980's. During my junior and senior years, I was able to upgrade to one of two Anschutz 1413's we had supplied to the team by our coach. The 52D's were Army JROTC rifles, and they were respected, accurate workhorses. Here's a photo of me shooting one, circa 1982, during informal JROTC practice. (Thus no shooting jacket or sling and glove) It could even be the same one you purchased. Is yours for sale?
