Two of my favorites is 23.2 of RL10x with a 55 grain Hornady soft point and 24 grains of AA2015 with the same Hornady soft point. They are even accurate in my skinny barrel Mini 14.

I have tweaked this load and bullet. I now use 23.4 of RL10x in gas guns and 23.2 in bolt actions. My next challenge is the AA2015. Same 55 grain Hornady but I will probably go down to a similar load with the AA2015. Others have mentioned the 63 grain SMP. I have loaded some with 24 grains of AA2460 for my bolt guns and 24.6 for the gas guns. They were already accurate but now that I have some time due to the social distancing it's time to play with this bullet and load. I typically use my Mini14 to test my loads. If I can make them shoot in that gun they will shoot well in anything.
