What is the best scope for the money for varmint hunting? I want a decent scope for under $200 canadian. I am looking at a tasco varmit/tactical 6-24X42 @ $189 is this scope good enough for the job, I do not need that high of quality as long as it is accuate and holds a zero, It will be going on a .270 that already has a bushnell 3-9X40. That is good enough for deer hunting but long range coyotes it is not good enough. Also i want somthing with mill dots. anybody use these scopes? With the weaver detachable rings can I have both of them sighted in on seperate rings and swich them without loss of zero?
