New Varmit Rifle?

I have a Leopold 3x9 as well as a 5 Star Redield 4x12 at my disposal. Not sure which way to go. Still looking on this one. Some folks i've been talking to are shooting 100 yd 3 shot groups they can cover with a dime with their 22.250. They claim they can shoot a 3 shot group at 600 yds and get em in a 3" circle. Time will tell.
