Have now used the ATP66 mounts from Sportsmatch on 4 rifles scopes being set up for FT. Once Optically zeroed adjusted the impact point of the pellets to 45yds after checking at 10yds.
Takes a little while as its only small adjustments are needed on the screw for the elevation. I actually used a small drop of screwlock on the ones that lock the moveable mount section for my own piece of mind.
My opinion is that they work well and for setting up FT scopes were moving the turret around the optical zero they are now bettered. Never tried any other make or used the windage version.
