I have 13 scopes, I have had many others, mainly they are all of the brands mentioned + Nikon,Swift and Tasco.
On some of them you pay a lot for the name, I think the most commen mistake is too much power and the parallex set to close. As far as brands go they all seem to be getting closer and closer the Swift and the Bushnell are the best dollar for value. While there are some better the differance in price is much bigger than the differance in value. I find a 1,75 X 4 Bushnell fills my needs quite well for my Omega although if I was to go shopping for that gun again I would look at some Swift models I am very impressed with my new Swift.
With the capability of going down to 2 or less power and having a large front optic you have good twilight capabilities and with 4 power you can shoot 1 hole groups @ 100yds on the range what else do you need. Lee
