Re: Explain the differences in optics
There are a few decent scopes made these days in the 200.00 dollar range. Anything less than that I wouldn't put on anything but a .22.
Termonology might be off, but less expensive glass will often times have a more of a black donut effect around the outside of the viewing field.
Quality optics will retain and repeat their zeros.
ie: Sighted in, you could adjust the scope say 8 clicks right, 8 click up (2" either way) Shoot a group and than readjust the scope back to where you had it and it'll be back where it should be.
Try that with a 50-100 scope and don't be surprised if it hasn't adjusted much or if it won't go back to zero.
High end scope with superior lenses and coatings will transmit more light. Some cheap scopes just make huge objectives to try and off set this.
If you ever have the chance to look at the 1000-2000 scopes, but know you'll never be able to afford them. Than don't look at all, it's hard to go back. I have two pairs of Swavorski binoculars and there's really only two other makers that have anything to even compete with them (my opinion)
90% of my scopes are Leupolds and they hold their own. There are equal or better scopes out there, but Leupold has one of the best warranties if you ever need it. I haven't, hopefully never will need to send one in.
If you on a budget take a look at the Bushnell 3200's or look for a used Leupold in that price range. Lots of them out there for 200-300.00
