that gun is a little spendy. I have it in a 22mag and I love it, If you want precision it's a great choice.
I chose the AR15 for varmit hunting though. Shooting .223 accurately and having up to 100rnds capacity is unstoppable. A bit overkill for most though. Whats reallygreat is shooting sage rats/prairie dogs all day and only needing to reload a couple times. Not to mention the parts availibility is insane and you can complete customize one down to your exact needs.
By the way, you can build an AR15 for 500bux. Bargain Bin guns are 450 from cmmg too...
This one is shooting sub moa with a match grade bbl. loves 69gr sierra gold metal match
