buckslayer,
That bushnell Trophy scope will be fine as long as you have enough eye relief. I have a Trophy in 1.75-4X32 on my Ultra Slug Hunter, it is very clear, bright and holds zero as good as any scope I have ever had. I am sure yours will be fine too. While Dave is very knowledgable, he makes his living off the industry. You DO NOT need a $300 scope on a shotgun! Like Markus stated, there are a lot of serviceable scopes out there, like the one you already have. Your Trophy is definitely NOT a "bad scope".
