The barrel is a 9 twist. I have fired 75 grain AMAX through it and they stabilize, but I haven't had time to go through load development with them, yet, so I don't know how well they will shoot.
Again without going through load development, it shows a lot of promise with 69 grain SMK's and CFE223, loaded to mag length. I shot a fast 10 round group @ 100 yards that went into less than an inch, with 5 of those rounds going into one ragged hole. With some tuning, I think that combo is going to be VERY accurate.
I want to work more with the 69 SMK's and do development with 53 VMAX's. With the heavies, I intend to use a single shot follower in the mag to allow me to tune seating depth.
IMO, the MVP Varmint is a feature packed rifle that gives a lot of value for the money. With Savage like features (barrel nut, an Accutrigger style trigger, and replaceable bolt head), the MVP also has a lot of potential for user customization later. I REALLY like this rifle!
