LRX without hesitation. Impact velocity determines range limitations, not muzzle velocity. As long as that bullet is impacting at 1800fps I'd pull the trigger. 1800 is my number, not Barnes' number. They say 1600 with an LRX. If a 127LRX from a 260 will put two holes in a cow elk from 725 yards and kill her within a couple steps of impact then your 145 will be overkill at 500.
