Varget/IMR 4064 worked best for me, RL19 good, and H414 is nigh identical to W760 which is what Rem used in their first factory load, the "140 CL" was actually the 139 SP over 47-49 gr W760. H380 faster burn and better for 100-120gr.

Zero 200 yds, 300 hold on back, 400 hold about a foot over.

I'd check a few first shot cold bore POI to verify. Often much closer to the POA than group size. Good Hunting and welcome to the Fire!
