I'm shooting a Marlin lever in .44 mag and having trouble getting it to group consistently. I'm trying to run 180 gr. loads (factory) but am just about ready to give up on these and try something else. Scope's a Redfield 2x-7x. At 50 yards the windage is good-right down the middle, but the elevation tends to be all over the target, from 2" high to 2" low. I don't think I'm asking too much to expect better than a 4" group at 50 yards. I've previously checked all the mounting screws on the base and rings, but will do that again. The scope seems to be parallax free as best as I can tell. I checked it off the bags out to 100 yards, and the crosshairs don't shift a bit. Other than playing with the loads, does this seem like a scope issue or what?
