In theory it would improve accuracy, however I don't think it's practical. For example a Spot Hogg Hog Father moves the same elevation in a single click that takes an Axcel Achieve XP 4 clicks. So the adjustments are finer for elevation, I think identical for windage, but the adjustments are more difficult to make on the Axcel. It has a release to rapidly slide, but then you still need to dial a little to get to the right spot.
I have several of both and I wouldn't entertain any dedicated target sight for hunting. Possibly a BE Exact 3d, as it has course adjustments, but I don't feel like any of the dedicated target sights are as durable as the hunting sights.
