I have a new 243 bolt action coming in. I have loaded some 100 gr. deer loads already. I want to load a coyote round now. I have 80 gr. NBT, and 70 gr. Sierra hpbt matchking. Powders I have are Varget, H4350, RL19, H380. What load would you suggest with these components? I would like a good amount of speed and accuracy.
