The 129 ABLR worked well for me on a smaller whitetail buck this year, fired from a SBR 6.5 Grendel. Impact velocity was probably around 2,100-2,150 fps, and it caused extensive damage in the chest cavity and a sizeable exit. It was more than enough gun for that whitetail, even though the Grendel is a smaller/slower cartridge. It's a good match for that bullet.
