I'm using the 142 6.5 ABLR in two rifles - 6.5x55 SE and a 264 WM. Accuracy has been very good in both of those rifles. Closest shot with either of them has been around 100 yards though. Exit wounds are large enough to give a blood trail, but everything I've shot with them has been DRT. They do prefer some jump. The 6.5x55 is .1 off the lands, the 264 is .05 off.
I use the regular AB's in three rifles as well - 2 - 25-06's and a 243. Accuracy is great. They too leave nice exits, with no blow-ups on shoulder shots. Don't be scared to run the further out. Try them out to .12 or so and see how they work in your rifles.
