Check
www.natchezss.com to see what Nitrex TR1 scopes are left. Nitrex and Weaver both owned by same company and Nitrex line was discontinued and Natchez sold them for less than 1/2 price. The TR1 scopes are very similiar to Weaver Grand Slams, made in Japan with darn good optics.
Have a Simmons 44mag scope on my Marlin XS7.....pretty decent scope
BSA Majestic DX scope. Have several of the highest power model. Good glass and features. All of mine on 257R or 6.5x55 Swedes and have performed well for me. Google BSA Majestic DX for sale and compare prices.
