The last scope I had to change out was a Lepold vxIII and put a Nikon in it's place. They all can go bad. The 44mag Simmons scopes are pretty bad but mostof their others seem to be well made. A close friend of mine has a .50 target rifle and he told me that two Lepolds had came apart on him, and now he has his spare which is and old Tasco and several hundred rounds havn't hurt it so far.I don't mind paying for quality, but I do mind paying for a name.
