Recommend scope for Ruger Target Gray

I took my Zeiss off my Ruger Target Grey in 22-250 and put it on my New Custom 300WBY and that is where it will stay. So, any recommendations for scope to shoot targets and varments? If anyone has a used scope he thinks would work and would sell let me know. I am trying to stay under 400.00. Help would be appriceated. thank you
