after lurking around on rimfirecentral.com and reading reviews I ordered a MKIItr and I really like it. I'm not a great shot and I have a cheap scope on mine so I could only get about an inch at 50 yards but I haven't tried many different kinds of ammo. I really need to get some decent glass on mine.
Awesome I love mine so far. The redfield scope I have is not very expensive at all you may want to take a look at those. Keep in mind the Redfield is a hunting Scope with Parallax set for 100yrds. I may eventiaully move this to my Winchester 270 and put my Nikon 3x9 Prostaff on here.
