Just picked up a T3 Lite in .223 as a training rifle. I've shot Tikka rifles before but never owned or set one up. Several questions about the rifle: 1) Putting a VX III 6.5-20x40 on it from another rig. What rings do I need to work with the integral base? I've been told the factory ones are not reliable. 2) Likely will not hand load for this rifle as I am trying to concentrate on handloads for other rigs. Twist is 1:9 and I have Hdy. 75 and Fed 69 gr. factory ammo. Any suggestions on what they usually like? 3) I checked Midway and spare magazines are expensive and "Coming Soon." Any alternatives? Thanks for any help!
