A few years back I took a Kimber Montana with a 6x SWFA MQ to Colorado to shoot Richardson ground squirrels. I had a ton of ammo loaded for it so it got the nod when my buddy gave me short notice.
Now, I'm not saying the 6x would be my first choice, but my hit count was very impressive out to 400 yards + and the Milquad reticle a veritable rock star!
Granted, the Richardsons are pachyderms compared to the tiny sage rats Ingwe is talking about.
