I currently have a Bushnell banner 6x-24x 40mm scope on my Remington 700 .308 that i use for bench shooting only. recently i noticed they have Bushnell elite 3200's 3x-10x for 150$, and 4200's for 200$. should i try to sell my banner and get a bushnell elite? will i notice a big difference? or should i just keep my high zoom banner? are there any advantages of a fixed 10x scope over a variable 3x-10x(i would use 10x all the time.)? Thanks in advance.
