I've got more Weaver scopes than any other from a 1-3x20 on a 45-70 to 36x on a 30BR.
I am very happy with the Japanese models and have replaced a couple Burris FFII with the Nitrex 3-9x40s, I see better with the Weaver scopes.
I've no experience with the 44-40 line but I like the "V", "T",Classic and Grand Slam scopes and have kept them.
I do own Burris, Leupold, Nikon, SWFA, Bushnell, Hawke and one Meuller as well.
