If the gun likes it, the 53 grain VMAX load should be good.
One I've had good luck with is the Nosler factory load using the 60 grain ballistic tips. If I could find it reliably I probably wouldn't handload for my AR. It's good .. scary good. Focus on the crosshairs while I pull the trigger and whatever is at the intersection of vertical and horizontal gets a hole in it, not merely near it. That silly gun, with that load, will compete with any factory varmint rifle I've ever owned shooting preferred handloads ... which is saying something IMHO.
