Hello All, I am working with my local JR small bore team and we currently have 5 Rem 513 light target rifles that we use for the youngest kids ( beginners). They have short stocks and are the perfect size. My problem is that all of them have bolts that are locked in place or come right out when extracting a spent round. This team has been in existance since 1940 and the guns are probably older than I am and have been shot alot. Does anyone know of a gunsmith that could repair these old guns? I gather that these are known for bolt problems. I am hoping somebody here can point me in the right direction, Thanks
