I use 2 loads for my AR that I shoot prairie dogs with then use the leftovers for coyotes with no issues.

50 gr vmax or NBT over 25.5 gr benchmark with CCI 400. Shoots accurate enough for prairie dogs and has killed every coyote I have shot at (so far). Shoots the same out of 3 different ARs and about .5ish moa +/- out of my bolt action.

40 gr vmax over 28 grs of varget (max load) with CCI 400. I have only shot 2 coyotes with this load but it put them down well.

Both loads seated to 2.23 to fit in the mags and easy to remember for the load data.
