I've been testing the 4.5-30x50 for FT use for about a month now. I am very impressed by the rangefinding capability of this scope on 30X. I am using a 4" sidewheel and the gaps between 45,50 & 55 yards are more than twice the width of those found on the new Nikko using the same size sidewheel. I use a 50ft adapter for ranges under 25 yards. The 50ft adapter enables ranges from 20 yards down to 10 yards on 30X. Ranges between 20 yards and 25 yards can be brought into focus by lowering the magnification. A couple of the lads from the Midlands had a go with my set up a few weeks back and have now purchased their own 4.5-30x50's
