I'm having a lot of trouble deciding what new scope to get. My B-day's coming up and I'm getting a new scope for my .223 varmint rifle. I really like the Bushnell Elite 4200 6-24x40 SF. I've also looked at Weaver Grand Slam, Vortex Viper, and Nikon Monarch in similar power ranges. I can't decide. I've grown fond of Bushnell Elites, but never used any of the other scopes. Any help or info would be great.
