I'm not GT, but I'll chime in on the 123 Amax vs. Scenar..... as I've shot a couple hundred of each outta the 6.5x47 and the .260 in the past few weeks.
Conclusion: They both pretty much kick azz. The Scenar did turn in the only sub-1/4" 5-shotter, and averaged .4" or so... but the Amax ran sub 1/2" all day, everyday. At longer ranges out to 800 or so, they shot the same... pretty much exactly. I shot the same drop chart for them both. If you want the hard data on it all, send me a PM and I'll send some along with pics and vids.
On Fur:
The Amax turfs schitt... hard. I blew one through a big blacktail buck at well inside 40 yards, and they hit coyotes like the hammer of Thor. I've killed about a dozen coyotes with 123 Amax, from 60 yards to 450.... every single one of them was down for the count on impact. They turn smaller stuff into wet puzzles in dramatic fashion.
I've only shot one coyote with the Scenar (200 yds).... I wasn't too fond of the results, though looking at the pic, I have no clue how this dog wore this hole for pert'near a quarter mile.
