I have a vx1 (2.5-7x32 I think) on a Marlin 1895mr (.450 Marlin).
The downside to friction is that if you need to adjust, you have to take the rifle from your shoulder so you can see how much you're adjusting. For me, that's not a big deal. Mine is zeroed at 100 yds and there it stays. An extremely long shot where I hunt might be 150 yds, but most are 35-100. I've shot about 100 rounds since zeroing and hasn't needed any readjustment. This rifle/scope combination sometimes shoots (off sandbags) 3 shot groups that can be completely covered by a quarter (coin), and usually 2 shots covered by the quarter, and half the third shot showing. I guess a little over 3" is my average on my hind legs. It's a good scope. Plenty bright on low power setting early morning.
