As an old Rochester NY boy, I probably owned every optic B&L ever made. They are still a fine scope, fully equal to a VX II. The mounts were klugey but the "swap the scope between rifles" idea seemed like a good idea at the time. Actually will swap with about 1 MOA error AFTER a few shots to seat things in.
I use Leupold Adjusto Mounts on mine as they are far better looking and work very well, as long as you don't want to swap the scope around. As long as your scope is clear and clean I'd have no fear of using it. I have the 1.5-5 on my 1952 Remington 721AC 300 H&H and it continues to kill everything it is pointed at and also shoots quite well for an unmodified 57 year old rifle with a 67 year old man behind it.
