The 129 ABLR worked well for me this year on one buck out of the 6.5 Gren. Angled shoulder and exit offside at ~125 yards. Muzzle velocity should be ~2400 with the load I was using...but I haven't checked it to verify so that's +/-.
The 129 ABLR has been a very good deer bullet for me out of the CM. From near to far I've almost always gotten exits and really impressive internal damage. I'm hopeful it will be just as good of a fit for the Grendel.
